* [SPARK-5038] Add explicit return type for implicit functions.Reynold Xin2014-12-316-63/+64
| | | | | | | | | | | | As we learned in #3580, not explicitly typing implicit functions can lead to compiler bugs and potentially unexpected runtime behavior. This is a follow up PR for rest of Spark (outside Spark SQL). The original PR for Spark SQL can be found at https://github.com/apache/spark/pull/3859 Author: Reynold Xin <rxin@databricks.com> Closes #3860 from rxin/implicit and squashes the following commits: 73702f9 [Reynold Xin] [SPARK-5038] Add explicit return type for implicit functions.

* [SPARK-5035] [Streaming] ReceiverMessage trait should extend SerializableJosh Rosen2014-12-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Spark Streaming's ReceiverMessage trait should extend Serializable in order to fix a subtle bug that only occurs when running on a real cluster: If you attempt to send a fire-and-forget message to a remote Akka actor and that message cannot be serialized, then this seems to lead to more-or-less silent failures. As an optimization, Akka skips message serialization for messages sent within the same JVM. As a result, Spark's unit tests will never fail due to non-serializable Akka messages, but these will cause mostly-silent failures when running on a real cluster. Before this patch, here was the code for ReceiverMessage: ``` /** Messages sent to the NetworkReceiver. */ private[streaming] sealed trait ReceiverMessage private[streaming] object StopReceiver extends ReceiverMessage ``` Since ReceiverMessage does not extend Serializable and StopReceiver is a regular `object`, not a `case object`, StopReceiver will throw serialization errors. As a result, graceful receiver shutdown is broken on real clusters (and local-cluster mode) but works in local modes. If you want to reproduce this, try running the word count example from the Streaming Programming Guide in the Spark shell: ``` import org.apache.spark._ import org.apache.spark.streaming._ import org.apache.spark.streaming.StreamingContext._ val ssc = new StreamingContext(sc, Seconds(10)) // Create a DStream that will connect to hostname:port, like localhost:9999 val lines = ssc.socketTextStream("localhost", 9999) // Split each line into words val words = lines.flatMap(_.split(" ")) import org.apache.spark.streaming.StreamingContext._ // Count each word in each batch val pairs = words.map(word => (word, 1)) val wordCounts = pairs.reduceByKey(_ + _) // Print the first ten elements of each RDD generated in this DStream to the console wordCounts.print() ssc.start() Thread.sleep(10000) ssc.stop(true, true) ``` Prior to this patch, this would work correctly in local mode but fail when running against a real cluster (it would report that some receivers were not shut down).

* SPARK-4547 [MLLIB] OOM when making bins in BinaryClassificationMetricsSean Owen2014-12-312-3/+92
| | | | | | | | | | | | | | | | Now that I've implemented the basics here, I'm less convinced there is a need for this change, somehow. Callers can downsample before or after. Really the OOM is not in the ROC curve code, but in code that might `collect()` it for local analysis. Still, might be useful to down-sample since the ROC curve probably never needs millions of points. This is a first pass. Since the `(score,label)` are already grouped and sorted, I think it's sufficient to just take every Nth such pair, in order to downsample by a factor of N? this is just like retaining every Nth point on the curve, which I think is the goal. All of the data is still used to build the curve of course. What do you think about the API, and usefulness?

* [SPARK-1010] Clean up uses of System.setProperty in unit testsJosh Rosen2014-12-3023-232/+216
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several of our tests call System.setProperty (or test code which implicitly sets system properties) and don't always reset/clear the modified properties, which can create ordering dependencies between tests and cause hard-to-diagnose failures. This patch removes most uses of System.setProperty from our tests, since in most cases we can use SparkConf to set these configurations (there are a few exceptions, including the tests of SparkConf itself). For the cases where we continue to use System.setProperty, this patch introduces a `ResetSystemProperties` ScalaTest mixin class which snapshots the system properties before individual tests and to automatically restores them on test completion / failure. See the block comment at the top of the ResetSystemProperties class for more details.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | common predicates This PR is a simplified version of several filter optimization rules introduced in #3778 authored by scwf. Newly introduced optimizations include: 1. `a && a` => `a` 2. `a || a` => `a` 3. `(a || b || c || ...) && (a || b || d || ...)` => `a && b && (c || d || ...)` The 3rd rule is particularly useful for optimizing the following query, which is planned into a cartesian product ```sql SELECT * FROM t1, t2 WHERE (t1.key = t2.key AND t1.value > 10) OR (t1.key = t2.key AND t2.value < 20) ``` to the following one, which is planned into an equi-join: ```sql SELECT * FROM t1, t2 WHERE t1.key = t2.key AND (t1.value > 10 OR t2.value < 20) ``` The example above is quite artificial, but common predicates are likely to appear in real life complex queries (like the one mentioned in #3778). A difference between this PR and #3778 is that these optimizations are not limited to `Filter`, but are generalized to all logical plan nodes. Thanks to scwf for bringing up these optimizations, and chenghao-intel for the generalization suggestion. <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/apache/spark/3784) <!-- Reviewable:end --> Author: Cheng Lian <lian@databricks.com> Closes #3784 from liancheng/normalize-filters and squashes the following commits: caca560 [Cheng Lian] Moves filter normalization into BooleanSimplification rule 4ab3a58 [Cheng Lian] Fixes test failure, adds more tests 5d54349 [Cheng Lian] Fixes typo in comment 2abbf8e [Cheng Lian] Forgot our sacred Apache licence header... cf95639 [Cheng Lian] Adds an optimization rule for filter normalization

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Addition of a very limited number of local matrix manipulation and generation methods that would be helpful in the further development for algorithms on top of BlockMatrix (SPARK-3974), such as Randomized SVD, and Multi Model Training (SPARK-1486). The proposed methods for addition are: For `Matrix` - map: maps the values in the matrix with a given function. Produces a new matrix. - update: the values in the matrix are updated with a given function. Occurs in place. Factory methods for `DenseMatrix`: - *zeros: Generate a matrix consisting of zeros - *ones: Generate a matrix consisting of ones - *eye: Generate an identity matrix - *rand: Generate a matrix consisting of i.i.d. uniform random numbers - *randn: Generate a matrix consisting of i.i.d. gaussian random numbers - *diag: Generate a diagonal matrix from a supplied vector *These methods already exist in the factory methods for `Matrices`, however for cases where we require a `DenseMatrix`, you constantly have to add `.asInstanceOf[DenseMatrix]` everywhere, which makes the code "dirtier". I propose moving these functions to factory methods for `DenseMatrix` where the putput will be a `DenseMatrix` and the factory methods for `Matrices` will call these functions directly and output a generic `Matrix`. Factory methods for `SparseMatrix`: - speye: Identity matrix in sparse format. Saves a ton of memory when dimensions are large, especially in Multi Model Training, where each row requires being multiplied by a scalar. - sprand: Generate a sparse matrix with a given density consisting of i.i.d. uniform random numbers. - sprandn: Generate a sparse matrix with a given density consisting of i.i.d. gaussian random numbers. - diag: Generate a diagonal matrix from a supplied vector, but is memory efficient, because it just stores the diagonal. Again, very helpful in Multi Model Training. Factory methods for `Matrices`: - Include all the factory methods given above, but return a generic `Matrix` rather than `SparseMatrix` or `DenseMatrix`. - horzCat: Horizontally concatenate matrices to form one larger matrix. Very useful in both Multi Model Training, and for the repartitioning of BlockMatrix. - vertCat: Vertically concatenate matrices to form one larger matrix. Very useful for the repartitioning of BlockMatrix.
