* [SQL] [Minor] Update the HiveContext UnittestCheng Hao2015-02-177-0/+17
| | | | | | | | | | | | | | | | | In unit test, the table src(key INT, value STRING) is not the same as HIVE src(key STRING, value STRING) https://github.com/apache/hive/blob/branch-0.13/data/scripts/q_test_init.sql And in the reflect.q, test failed for expression `reflect("java.lang.Integer", "valueOf", key, 16)`, which expect the argument `key` as STRING not INT. This PR doesn't aim to change the `src` schema, we can do that after 1.3 released, however, we probably need to re-generate all the golden files.

* [SQL] Optimize arithmetic and predicate operatorskai2015-02-1610-260/+290
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Existing implementation of arithmetic operators and BinaryComparison operators have redundant type checking codes, e.g.: Expression.n2 is used by Add/Subtract/Multiply. (1) n2 always checks left.dataType == right.dataType. However, this checking should be done once when we resolve expression types; (2) n2 requires dataType is a NumericType. This can be done once. This PR optimizes arithmetic and predicate operators by removing such redundant type-checking codes. Some preliminary benchmarking on 10G TPC-H data over 5 r3.2xlarge EC2 machines shows that this PR can reduce the query time by 5.5% to 11%. The benchmark queries follow the template below, where OP is plus/minus/times/divide/remainder/bitwise and/bitwise or/bitwise xor. SELECT l_returnflag, l_linestatus, SUM(l_quantity OP cnt1), SUM(l_quantity OP cnt2), ...., SUM(l_quantity OP cnt700) FROM ( SELECT l_returnflag, l_linestatus, l_quantity, 1 AS cnt1, 2 AS cnt2, ..., 700 AS cnt700 FROM lineitem WHERE l_shipdate <= '1998-09-01' ) GROUP BY l_returnflag, l_linestatus; Author: kai <kaizeng@eecs.berkeley.edu> Closes #4472 from kai-zeng/arithmetic-optimize and squashes the following commits: fef0cf1 [kai] Merge branch 'master' of github.com:apache/spark into arithmetic-optimize 4b3a1bb [kai] chmod a-x 5a41e49 [kai] chmod a-x Expression.scala cb37c94 [kai] rebase onto spark master 7f6e968 [kai] chmod 100755 -> 100644 6cddb46 [kai] format 7490dbc [kai] fix unresolved-expression exception for EqualTo 9c40bc0 [kai] fix bitwisenot 3cbd363 [kai] clean up test code ca47801 [kai] override evalInternal for bitwise ops 8fa84a1 [kai] add bitwise or and xor 6892fc4 [kai] revert override evalInternal f8eba24 [kai] override evalInternal 31ccdd4 [kai] rewrite all bitwise op and remove evalInternal 86297e2 [kai] generalized cb92ae1 [kai] bitwise-and: override eval 97a7d6c [kai] bitwise-and: override evalInternal using and func 0906c39 [kai] add bitwise test 62abbbc [kai] clean up predicate and arithmetic b34d58d [kai] add caching and benmark option 12c5b32 [kai] override eval 1cd7571 [kai] fix sqrt and maxof 03fd0c3 [kai] fix predicate 16fd84c [kai] optimize + - * / % -(unary) abs < > <= >= fd95823 [kai] remove unnecessary type checking 24d062f [kai] test suite

* [SQL] [Minor] Update the SpecificMutableRow.copyCheng Hao2015-02-161-3/+4
| | | | | | | | | | When profiling the Join / Aggregate queries via VisualVM, I noticed lots of `SpecificMutableRow` objects created, as well as the `MutableValue`, since the `SpecificMutableRow` are mostly used in data source implementation, but the `copy` method could be called multiple times in upper modules (e.g. in Join / aggregation etc.), duplicated instances created should be avoid.

Now users can also overwriting and appending to existing tables. Notice that inserting into partitioned tables is not supported yet. When Parquet data source is enabled, insertion to Hive Metastore Parquet tables is also fullfilled by the Parquet data source. This is done by the newly introduced `HiveMetastoreCatalog.ParquetConversions` rule, which is a "proper" implementation of the original hacky `HiveStrategies.ParquetConversion`. The latter is still preserved, and can be removed together with the old Parquet support in the future.
