------------------------------------------
Summary: udaf_percentile_approx.q fails with Hadoop 0.23.5 when
map-side aggr is disabled.
Key: HIVE-3911
URL: https://issues.apache.org/jira/browse/HIVE-3911
Project: Hive
Issue Type: Bug
Affects Versions: 0.10.0
Reporter: Thiruvel Thirumoolan
Fix For: 0.10.0, 0.11.0
I am running Hive10 unit tests against Hadoop 0.23.5 and
udaf_percentile_approx.q fails with a different value when map-side aggr is
disabled and only when 3rd argument to this UDAF is 100. Matches expected
output when map-side aggr is enabled for the same arguments.
This test passes when hadoop.version is 1.1.1 and fails when its 0.23.x or
2.0.0-alpha or 2.0.2-alpha.
