* [SPARK-8638] [SQL] Window Function Performance ImprovementsHerman van Hovell2015-07-181-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## Description Performance improvements for Spark Window functions. This PR will also serve as the basis for moving away from Hive UDAFs to Spark UDAFs. See JIRA tickets SPARK-8638 and SPARK-7712 for more information. ## Improvements * Much better performance (10x) in running cases (e.g. BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) and UNBOUDED FOLLOWING cases. The current implementation in spark uses a sliding window approach in these cases. This means that an aggregate is maintained for every row, so space usage is N (N being the number of rows). This also means that all these aggregates all need to be updated separately, this takes N*(N-1)/2 updates. The running case differs from the Sliding case because we are only adding data to an aggregate function (no reset is required), we only need to maintain one aggregate (like in the UNBOUNDED PRECEDING AND UNBOUNDED case), update the aggregate for each row, and get the aggregate value after each update. This is what the new implementation does. This approach only uses 1 buffer, and only requires N updates; I am currently working on data with window sizes of 500-1000 doing running sums and this saves a lot of time. The CURRENT ROW AND UNBOUNDED FOLLOWING case also uses this approach and the fact that aggregate operations are communitative, there is one twist though it will process the input buffer in reverse. * Fewer comparisons in the sliding case. The current implementation determines frame boundaries for every input row. The new implementation makes more use of the fact that the window is sorted, maintains the boundaries, and only moves them when the current row order changes. This is a minor improvement. * A single Window node is able to process all types of Frames for the same Partitioning/Ordering. This saves a little time/memory spent buffering and managing partitions. This will be enabled in a follow-up PR. * A lot of the staging code is moved from the execution phase to the initialization phase. Minor performance improvement, and improves readability of the execution code. ## Benchmarking I have done a small benchmark using [on time performance](http://www.transtats.bts.gov) data of the month april. I have used the origin as a partioning key, as a result there is quite some variation in window sizes. The code for the benchmark can be found in the JIRA ticket. These are the results per Frame type: Frame | Master | SPARK-8638 ----- | ------ | ---------- Entire Frame | 2 s | 1 s Sliding | 18 s | 1 s Growing | 14 s | 0.9 s Shrinking | 13 s | 1 s Author: Herman van Hovell <hvanhovell@questtec.nl> Closes #7057 from hvanhovell/SPARK-8638 and squashes the following commits: 3bfdc49 [Herman van Hovell] Fixed Perfomance Regression for Shrinking Window Frames (+Rebase) 2eb3b33 [Herman van Hovell] Corrected reverse range frame processing. 2cd2d5b [Herman van Hovell] Corrected reverse range frame processing. b0654d7 [Herman van Hovell] Tests for exotic frame specifications. e75b76e [Herman van Hovell] More docs, added support for reverse sliding range frames, and some reorganization of code. 1fdb558 [Herman van Hovell] Changed Data In HiveDataFrameWindowSuite. ac2f682 [Herman van Hovell] Added a few more comments. 1938312 [Herman van Hovell] Added Documentation to the createBoundOrdering methods. bb020e6 [Herman van Hovell] Major overhaul of Window operator.

* [SPARK-9150][SQL] Create CodegenFallback and Unevaluable traitReynold Xin2015-07-1822-199/+194
| | | | | | | | | | | | | | | | It is very hard to track which expressions have code gen implemented or not. This patch removes the default fallback gencode implementation from Expression, and moves that into a new trait called CodegenFallback. Each concrete expression needs to either implement code generation, or mix in CodegenFallback. This makes it very easy to track which expressions have code generation implemented already. Additionally, this patch creates an Unevaluable trait that can be used to track expressions that don't support evaluation (e.g. Star).

| | | | | | | | | | | | | | fix 2 bugs introduced in https://github.com/apache/spark/pull/7353 1. we should use UTC Calendar when cast string to date . Before #7353 , we use `DateTimeUtils.fromJavaDate(Date.valueOf(s.toString))` to cast string to date, and `fromJavaDate` will call `millisToDays` to avoid the time zone issue. Now we use `DateTimeUtils.stringToDate(s)`, we should create a Calendar with UTC in the begging. 2. we should not change the default time zone in test cases. The `threadLocalLocalTimeZone` and `threadLocalTimestampFormat` in `DateTimeUtils` will only be evaluated once for each thread, so we can't set the default time zone back anymore.

* [SPARK-9085][SQL] Remove LeafNode, UnaryNode, BinaryNode from TreeNode.Reynold Xin2015-07-1610-60/+56
| | | | | | | | | | | | | | | | This builds on #7433 but also removes LeafNode/UnaryNode. These are slightly more complicated to remove. I had to change some abstract classes to traits in order for it to work. The problem with LeafNode/UnaryNode is that they are often mixed in at the end of an Expression, and then the toString function actually gets resolved to the ones defined in TreeNode, rather than in Expression.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Jira https://issues.apache.org/jira/browse/SPARK-8995 In PR #6981we noticed that we cannot cast date strings that contains a time, like '2015-03-18 12:39:40' to date. Besides it's not possible to cast a string like '18:03:20' to a timestamp. If a time is passed without a date, today is inferred as date.

* [SPARK-8972] [SQL] Incorrect result for rollupCheng Hao2015-07-151-3/+39
| | | | | | | | | | | | | | | | | We don't support the complex expression keys in the rollup/cube, and we even will not report it if we have the complex group by keys, that will cause very confusing/incorrect result. e.g. `SELECT key%100 FROM src GROUP BY key %100 with ROLLUP` This PR adds an additional project during the analyzing for the complex GROUP BY keys, and that projection will be the child of `Expand`, so to `Expand`, the GROUP BY KEY are always the simple key(attribute names).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the following changes: 1. ExpectsInputTypes only defines expected input types, but does not perform any implicit type casting. 2. ImplicitCastInputTypes is a new trait that defines both expected input types, as well as performs implicit type casting. 3. BinaryOperator has a new abstract function "inputType", which defines the expected input type for both left/right. Concrete BinaryOperator expressions no longer perform any implicit type casting. 4. For BinaryOperators, convert NullType (i.e. null literals) into some accepted type so BinaryOperators don't need to handle NullTypes. TODOs needed: fix unit tests for error reporting. I'm intentionally not changing anything in aggregate expressions because yhuai is doing a big refactoring on that right now.

| | | | | | | | | | | | | | | | | | | | | existing uses This pull request adds a Scalastyle regex rule which fails the style check if `Class.forName` is used directly. `Class.forName` always loads classes from the default / system classloader, but in a majority of cases, we should be using Spark's own `Utils.classForName` instead, which tries to load classes from the current thread's context classloader and falls back to the classloader which loaded Spark when the context classloader is not defined. <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/apache/spark/7350) <!-- Reviewable:end --> Author: Josh Rosen <joshrosen@databricks.com> Closes #7350 from JoshRosen/ban-Class.forName and squashes the following commits: e3e96f7 [Josh Rosen] Merge remote-tracking branch 'origin/master' into ban-Class.forName c0b7885 [Josh Rosen] Hopefully fix the last two cases d707ba7 [Josh Rosen] Fix uses of Class.forName that I missed in my first cleanup pass 046470d [Josh Rosen] Merge remote-tracking branch 'origin/master' into ban-Class.forName 62882ee [Josh Rosen] Fix uses of Class.forName or add exclusion. d9abade [Josh Rosen] Add stylechecker rule to ban uses of Class.forName
