[jira] [Commented] (HIVE-13107) LLAP: Rotate GC logs periodically
to prevent full disks
[ https://issues.apache.org/jira/browse/HIVE-13107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15155327#comment-15155327 ]
Prasanth Jayachandran commented on HIVE-13107:
----------------------------------------------
Also we should consider using -XX:+PrintGCDateStamps instead of -XX:+PrintGCTimeStamps.
{code}
-XX:+PrintGCTimeStamps -> 0,185: [GC 66048K->53077K(251392K), 0,0977580 secs]
-XX:+PrintGCDateStamps -> 2014-01-03T12:08:38.102-0100: [GC 66048K->53077K(251392K), 0,0959470 secs]
{code}
Easier to correlate with log lines.
