     [ https://issues.apache.org/jira/browse/TEZ-1263?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Rajesh Balamohan resolved TEZ-1263.
-----------------------------------

    Resolution: Won't Fix

Tried CRC32C with 'org.apache.hadoop.util.TestPureJavaCrc32$PerformanceTest' benchmark.  Didn't see significant gains with CRC32C.  Hence, marking as won't fix for now.
