21ec49e810 IMPALA-150: Performing dynamic partition insert via Impala on "large" table fails and takes down HDFS 
This is solved by repartitioning the input to the hdfs table sinks on the partition key columns of the hdfs
table, so that each partition is only written by a single node.

e218721386 IMPALA-198: Support setting file format, table comment in CREATE TABLE LIKE statements 2014-01-08 10:49:31 -08:00
Marcel Kornacker
d7e22f44bb Partitioned hash joins 
- added PlanNode.numNodes, PlanNode.avgRowSize and PlanNode.computeStats()
- fixing up some cardinality estimates
- Planner now tries to do a cost-based decision between broadcast join and join with full repartitioning (both inputs)
- ExchangeNode now distinguishes between its input and output row descriptor: the output potentially contains more tuples
- fixed problem related to cancellation and concurrent hash table builds.

Not included:
- partitioned joins that take advantage of existing partitions of the inputs; those will have to wait for a follow-on change

36e9fe1c1a Run compute table stats statements using Hive CLI 
This works around a problem with computing table stats via the Hive Meta Store client
API. When executing these stements via the MetaStoreClient, all tables were getting a
num_rows=0 value returned from the ANALYZE TABLE query.
