Date Fri, 28 Apr 2017 03:14:58 GMT
Hello Jenkins,

I'd like you to reexamine a change.  Please visit

to look at the new patch set (#4).

Change subject: ASTERIXDB-1892: Sets a proper hash table cardinality during hash-group by

ASTERIXDB-1892: Sets a proper hash table cardinality during hash-group by

 - Set a proper hash table cardinality during the merge phase
   of the external hash group-by operator.
 - Currently, the number of tuples in a spilled partition is
   used as the hash table cardinality. And this can cause an issue
   since compiler.groupmemory size is not considered.
 - So, like the initial group-by build phase, the hash table
   cardinality will be set properly based on the memory budget for
   the group-by operator.
 - Add a functionality that also compacts the header frames of
   the given hash table when compacting the content frames.
