Subject [jira] [Commented] (PHOENIX-2301) NullPointerException when upserting into a char array column
Date Thu, 05 Nov 2015 15:17:27 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-2301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14991788#comment-14991788
] 

James Taylor commented on PHOENIX-2301:
---------------------------------------

I see - so there's no NPE? Let's rename the JIRA summary then. We don't
enforce any array size constraints, so let's not add that check. Your
original idea of skipping the check for array types is fine (as long as
we're validating the individual element constraint).
