Subject [jira] Commented: (MAPREDUCE-2193) 13 Findbugs warnings on trunk and branch-0.22
Date Fri, 11 Feb 2011 05:28:57 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2193?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12993351#comment-12993351
] 

Priyo Mustafi commented on MAPREDUCE-2193:
------------------------------------------

Looks like https://issues.apache.org/jira/browse/MAPREDUCE-2026 removed synchronization from
JobInProgress.getCounters() to make the lock more granular.  This has added two findbugs now.
Should these be ignored then as it was done on purpose?
