* [SPARK-4740] Create multiple concurrent connections between two peer nodes ↵Reynold Xin2014-12-093-46/+180
| | | | | | | | | | | | | | | | | | | | | in Netty. It's been reported that when the number of disks is large and the number of nodes is small, Netty network throughput is low compared with NIO. We suspect the problem is that only a small number of disks are utilized to serve shuffle files at any given point, due to connection reuse. This patch adds a new config parameter to specify the number of concurrent connections between two peer nodes, default to 2.

* [SPARK-4785][SQL] Initilize Hive UDFs on the driver and serialize them with ↵Cheng Hao2014-12-095-50/+173
| | | | | | | | | | | | | | | | | | | | a wrapper Different from Hive 0.12.0, in Hive 0.13.1 UDF/UDAF/UDTF (aka Hive function) objects should only be initialized once on the driver side and then serialized to executors. However, not all function objects are serializable (e.g. GenericUDF doesn't implement Serializable). Hive 0.13.1 solves this issue with Kryo or XML serializer. Several utility ser/de methods are provided in class o.a.h.h.q.e.Utilities for this purpose. In this PR we chose Kryo for efficiency. The Kryo serializer used here is created in Hive. Spark Kryo serializer wasn't used because there's no available SparkConf instance.

* [Release] Correctly translate contributors name in release notesAndrew Or2014-12-034-56/+230
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit involves three main changes: (1) It separates the translation of contributor names from the generation of the contributors list. This is largely motivated by the Github API limit; even if we exceed this limit, we should at least be able to proceed manually as before. This is why the translation logic is abstracted into its own script translate-contributors.py. (2) When we look for candidate replacements for invalid author names, we should look for the assignees of the associated JIRAs too. As a result, the intermediate file must keep track of these. (3) This provides an interactive mode with which the user can sit at the terminal and manually pick the candidate replacement that he/she thinks makes the most sense. As before, there is a non-interactive mode that picks the first candidate that the script considers "valid." TODO: We should have a known_contributors file that stores known mappings so we don't have to go through all of this translation every time. This is also valuable because some contributors simply cannot be automatically translated. Conflicts: .gitignore
* [SPARK-4580] [SPARK-4610] [mllib] [docs] Documentation for tree ensembles + ↵Joseph K. Bradley2014-12-0419-182/+1140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DecisionTree API fix Major changes: * Added programming guide sections for tree ensembles * Added examples for tree ensembles * Updated DecisionTree programming guide with more info on parameters * **API change**: Standardized the tree parameter for the number of classes (for classification) Minor changes: * Updated decision tree documentation * Updated existing tree and tree ensemble examples * Use train/test split, and compute test error instead of training error. * Fixed decision_tree_runner.py to actually use the number of classes it computes from data. (small bug fix) Note: I know this is a lot of lines, but most is covered by: * Programming guide sections for gradient boosting and random forests. (The changes are probably best viewed by generating the docs locally.) * New examples (which were copied from the programming guide) * The "numClasses" renaming I have run all examples and relevant unit tests.
