The checker tries to follow as closely as possible the guidelines of the code style document, and makes some decisions where the guide is not clear. In particular: - wildcard imports come first when there are other imports in the same package - multi-import blocks come before single imports - lower-case names inside multi-import blocks come before others In some projects, such as graphx, there seems to be a convention to separate o.a.s imports from the project's own; to simplify the checker, I chose not to allow that, which is a strict interpretation of the code style guide, even though I think it makes sense. Since the checks are based on syntax only, some edge cases may generate spurious warnings; for example, when class names start with a lower case letter (and are thus treated as a package name by the checker). The checker is currently only generating warnings, and since there are many of those, the build output does get a little noisy. The idea is to fix the code (and the checker, as needed) little by little instead of having a huge change that touches everywhere.

jira: https://issues.apache.org/jira/browse/SPARK-11605 Check Java compatibility for MLlib for this release. fix: 1. `StreamingTest.registerStream` needs java friendly interface. 2. `GradientBoostedTreesModel.computeInitialPredictionAndError` and `GradientBoostedTreesModel.updatePredictionError` has java compatibility issue. Mark them as `developerAPI`. TBD: [updated] no fix for now per discussion. `org.apache.spark.mllib.classification.LogisticRegressionModel` `public scala.Option<java.lang.Object> getThreshold();` has wrong return type for Java invocation. `SVMModel` has the similar issue. Yet adding a `scala.Option<java.util.Double> getThreshold()` would result in an overloading error due to the same function signature. And adding a new function with different name seems to be not necessary. cc jkbradley feynmanliang Author: Yuhao Yang <hhbyyh@gmail.com> Closes #10102 from hhbyyh/javaAPI.

This PR contains the following updates: - Created a new private variable `boundTEncoder` that can be shared by multiple functions, `RDD`, `select` and `collect`. - Replaced all the `queryExecution.analyzed` by the function call `logicalPlan` - A few API comments are using wrong class names (e.g., `DataFrame`) or parameter names (e.g., `n`) - A few API descriptions are wrong.

The reason is that TrackStateRDDs generated by trackStateByKey expect the previous batch's TrackStateRDDs to have a partitioner. However, when recovery from DStream checkpoints, the RDDs recovered from RDD checkpoints do not have a partitioner attached to it. This is because RDD checkpoints do not preserve the partitioner (SPARK-12004). While #9983 solves SPARK-12004 by preserving the partitioner through RDD checkpoints, there may be a non-zero chance that the saving and recovery fails. To be resilient, this PR repartitions the previous state RDD if the partitioner is not detected. Author: Tathagata Das <tathagata.das1565@gmail.com> Closes #9988 from tdas/SPARK-11932.

This PR: 1. Suppress all known warnings. 2. Cleanup test cases and fix some errors in test cases. 3. Fix errors in HiveContext related test cases. These test cases are actually not run previously due to a bug of creating TestHiveContext. 4. Support 'testthat' package version 0.11.0 which prefers that test cases be under 'tests/testthat' 5. Make sure the default Hadoop file system is local when running test cases. 6. Turn on warnings into errors. Author: Sun Rui <rui.sun@intel.com> Closes #10030 from sun-rui/SPARK-12034.

Currently, the order of joins is exactly the same as SQL query, some conditions may not pushed down to the correct join, then those join will become cross product and is extremely slow. This patch try to re-order the inner joins (which are common in SQL query), pick the joins that have self-contain conditions first, delay those that does not have conditions. After this patch, the TPCDS query Q64/65 can run hundreds times faster. cc marmbrus nongli Author: Davies Liu <davies@databricks.com> Closes #10073 from davies/reorder_joins.
