      Description

      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.
