Marquis Wang updated HIVE-1803:
-------------------------------
Attachment: HIVE-1803.2.patch
We fixed the problem in BitmapCollectSet by looking at the PercentileApprox
UDAF to figure out how to use an array an input to a UDAF.
This new patch is a working implementation of bitmap indexing. The new test
index_bitmap.q shows how to use the index. However, I am unable to add the test
itself, and get errors when I run
ant test -Dtestcase=TestCliDriver -Dqfile=index_bitmap.q -Doverwrite=true
-Dtest.silent=false
It says
Exception: java.lang.RuntimeException: The table
default__srcpart_srcpart_index_proj__ is an index table. Please do drop index
instead.
wrt to the ALTER INDEX REBUILD line in the test.
We're pretty confused about whether we're doing the new test incorrectly and
would appreciate any help.
While we're working to get around that we're also going to go ahead and work on
a compressed bitmap, since this implementation does no compression.
