* [SPARK-1089] fix the regression problem on ADD_JARS in 0.9CodingCat2014-02-261-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://spark-project.atlassian.net/browse/SPARK-1089 copied from JIRA, reported by @ash211 "Using the ADD_JARS environment variable with spark-shell used to add the jar to both the shell and the various workers. Now it only adds to the workers and importing a custom class in the shell is broken. The workaround is to add custom jars to both ADD_JARS and SPARK_CLASSPATH. We should fix ADD_JARS so it works properly again. See various threads on the user list: https://mail-archives.apache.org/mod_mbox/incubator-spark-user/201402.mbox/%3CCAJbo4neMLiTrnm1XbyqomWmp0m+EUcg4yE-txuRGSVKOb5KLeA@mail.gmail.com%3E (another one that doesn't appear in the archives yet titled "ADD_JARS not working on 0.9")" The reason of this bug is two-folds in the current implementation of SparkILoop.scala, the settings.classpath is not set properly when the process() method is invoked the weird behaviour of Scala 2.10, (I personally thought it is a bug) if we simply set value of a PathSettings object (like settings.classpath), the isDefault is not set to true (this is a flag showing if the variable is modified), so it makes the PathResolver loads the default CLASSPATH environment variable value to calculated the path (see https://github.com/scala/scala/blob/2.10.x/src/compiler/scala/tools/util/PathResolver.scala#L215) what we have to do is to manually make this flag set, (https://github.com/CodingCat/incubator-spark/blob/e3991d97ddc33e77645e4559b13bf78b9e68239a/repl/src/main/scala/org/apache/spark/repl/SparkILoop.scala#L884) Author: CodingCat <zhunansjtu@gmail.com> Closes #13 from CodingCat/SPARK-1089 and squashes the following commits: 8af81e7 [CodingCat] impose non-null settings 9aa2125 [CodingCat] code cleaning ce36676 [CodingCat] code cleaning e045582 [CodingCat] fix the regression problem on ADD_JARS in 0.9

* SPARK-1071: Tidy logging strategy and use of log4jSean Owen2014-02-2311-69/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prompted by a recent thread on the mailing list, I tried and failed to see if Spark can be made independent of log4j. There are a few cases where control of the underlying logging is pretty useful, and to do that, you have to bind to a specific logger. Instead I propose some tidying that leaves Spark's use of log4j, but gets rid of warnings and should still enable downstream users to switch. The idea is to pipe everything (except log4j) through SLF4J, and have Spark use SLF4J directly when logging, and where Spark needs to output info (REPL and tests), bind from SLF4J to log4j. This leaves the same behavior in Spark. It means that downstream users who want to use something except log4j should: - Exclude dependencies on log4j, slf4j-log4j12 from Spark - Include dependency on log4j-over-slf4j - Include dependency on another logger X, and another slf4j-X - Recreate any log config that Spark does, that is needed, in the other logger's config That sounds about right. Here are the key changes: - Include the jcl-over-slf4j shim everywhere by depending on it in core. - Exclude dependencies on commons-logging from third-party libraries. - Include the jul-to-slf4j shim everywhere by depending on it in core. - Exclude slf4j-* dependencies from third-party libraries to prevent collision or warnings - Added missing slf4j-log4j12 binding to GraphX, Bagel module tests And minor/incidental changes: - Update to SLF4J 1.7.5, which happily matches Hadoop 2’s version and is a recommended update over 1.7.2 - (Remove a duplicate HBase dependency declaration in SparkBuild.scala) - (Remove a duplicate mockito dependency declaration that was causing warnings and bugging me) Author: Sean Owen <sowen@cloudera.com> Closes #570 from srowen/SPARK-1071 and squashes the following commits: 52eac9f [Sean Owen] Add slf4j-over-log4j12 dependency to core (non-test) and remove it from things that depend on core. 77a7fa9 [Sean Owen] SPARK-1071: Tidy logging strategy and use of log4j

* [SPARK-1113] External spilling - fix Int.MaxValue hash code collision bugAndrew Or2014-02-212-38/+102
| | | | | | | | | | | | | | | | | | | | The original poster of this bug is @guojc, who opened a PR that preceded this one at https://github.com/apache/incubator-spark/pull/612. ExternalAppendOnlyMap uses key hash code to order the buffer streams from which spilled files are read back into memory. When a buffer stream is empty, the default hash code for that stream is equal to Int.MaxValue. This is, however, a perfectly legitimate candidate for a key hash code. When reading from a spilled map containing such a key, a hash collision may occur, in which case we attempt to read from an empty stream and throw NoSuchElementException. The fix is to maintain the invariant that empty buffer streams are never added back to the merge queue to be considered. This guarantees that we never read from an empty buffer stream, ever again. This PR also includes two new tests for hash collisions.

* MLLIB-25: Implicit ALS runs out of memory for moderately large numbers of ↵Sean Owen2014-02-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | features There's a step in implicit ALS where the matrix `Yt * Y` is computed. It's computed as the sum of matrices; an f x f matrix is created for each of n user/item rows in a partition. In `ALS.scala:214`: ``` factors.flatMapValues{ case factorArray => factorArray.map{ vector => val x = new DoubleMatrix(vector) x.mmul(x.transpose()) } }.reduceByKeyLocally((a, b) => a.addi(b)) .values .reduce((a, b) => a.addi(b)) ``` Completely correct, but there's a subtle but quite large memory problem here. map() is going to create all of these matrices in memory at once, when they don't need to ever all exist at the same time. For example, if a partition has n = 100000 rows, and f = 200, then this intermediate product requires 32GB of heap. The computation will never work unless you can cough up workers with (more than) that much heap. Fortunately there's a trivial change that fixes it; just add `.view` in there.

* MLLIB-22. Support negative implicit input in ALSSean Owen2014-02-193-21/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm back with another less trivial suggestion for ALS: In ALS for implicit feedback, input values are treated as weights on squared-errors in a loss function (or rather, the weight is a simple function of the input r, like c = 1 + alpha*r). The paper on which it's based assumes that the input is positive. Indeed, if the input is negative, it will create a negative weight on squared-errors, which causes things to go haywire. The optimization will try to make the error in a cell as large possible, and the result is silently bogus. There is a good use case for negative input values though. Implicit feedback is usually collected from signals of positive interaction like a view or like or buy, but equally, can come from "not interested" signals. The natural representation is negative values. The algorithm can be extended quite simply to provide a sound interpretation of these values: negative values should encourage the factorization to come up with 0 for cells with large negative input values, just as much as positive values encourage it to come up with 1. The implications for the algorithm are simple: * the confidence function value must not be negative, and so can become 1 + alpha*|r| * the matrix P should have a value 1 where the input R is _positive_, not merely where it is non-zero. Actually, that's what the paper already says, it's just that we can't assume P = 1 when a cell in R is specified anymore, since it may be negative This in turn entails just a few lines of code change in `ALS.scala`: * `rs(i)` becomes `abs(rs(i))` * When constructing `userXy(us(i))`, it's implicitly only adding where P is 1. That had been true for any us(i) that is iterated over, before, since these are exactly the ones for which P is 1. But now P is zero where rs(i) <= 0, and should not be added I think it's a safe change because: * It doesn't change any existing behavior (unless you're using negative values, in which case results are already borked) * It's the simplest direct extension of the paper's algorithm * (I've used it to good effect in production FWIW) Tests included. I tweaked minor things en route: * `ALS.scala` javadoc writes "R = Xt*Y" when the paper and rest of code defines it as "R = X*Yt" * RMSE in the ALS tests uses a confidence-weighted mean, but the denominator is not actually sum of weights Excuse my Scala style; I'm sure it needs tweaks.
