c2cfc7e2a3 IMPALA-373: Add support for 'LOAD DATA' statements 
This change adds Impala support for LOAD DATA statements. This allows the user
to load one or more files into a table or partition from a given HDFS location. The
load operation only moves files, it does not convert data to match the target
table/partition's file format.

b1de018298 IMPALA-31 Support EXPLAIN <query> 
Hue is moving to HiveServer2 but HiveServer2 does not have an "explain" RPC
call. To support "explain", I added it to the language.

An "explain" statement will return a result set: one row per explain line.

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
