Patch Set 3: (2 comments) http://gerrit.cloudera.org:8080/#/c/21455/2/be/src/exec/hash-table.cc File be/src/exec/hash-table.cc: http://gerrit.cloudera.org:8080/#/c/21455/2/be/src/exec/hash-table.cc@373 PS2, Line 373: t int sample_size > Looks like the 64 is the sampling number, can we give the 64 a const, and r Done. Keeping it local for this Init method. Picked 64 because MemUsage account for Bitmap::MemUsage as well, which cost 8 bytes per 64 entries. http://gerrit.cloudera.org:8080/#/c/21455/2/be/src/exec/hash-table.cc@378 PS2, Line 378: // TODO: Add 'mem_ > Should "if (capacity_ > 0)" also hold the DCHECK? Or is it possible that th capacity_ is capped to 1 at minimum. It is unlikely, but we want to know if this indeed happen.
