Subject [jira] [Commented] (HIVE-4220) TimestampWritable.toString throws array index exception sometimes
Date Sat, 06 Apr 2013 23:23:16 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13624532#comment-13624532
] 

Ashutosh Chauhan commented on HIVE-4220:
----------------------------------------

Since there is no test-case, I am having hard time envisioning the scenario where this might
occur. Is it that there is a concurrent access of this non-thread-safe formatter where this
will occur? Explaining the scenario where this bug will showup will be useful.
