[jira] [Updated] (PIG-2999) Regression after PIG-2975: BinInterSedesTupleRawComparator secondary sort failing

["Koji Noguchi (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-2999?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Koji Noguchi updated PIG-2999:
------------------------------

    Attachment: pig-2999-v1.txt

During the performance test in pig-2975, I made a change inside compareBinInterSedesDatum for bytearray comparisons but didn't update the bytebuffer position after the read leading to random failures when bytebuffer is accessed afterwards.

> I think I broke the build from PIG-2975.  I see couple of tests failing at BinInterSedesTupleRawComparator.
