Subject [jira] [Commented] (PHOENIX-5101) ScanningResultIterator getScanMetrics throws NPE
Date Fri, 03 May 2019 06:38:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-5101?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16832287#comment-16832287

Karan Mehta commented on PHOENIX-5101:
--------------------------------------

Nice catch @tdsilva and thanks for the fix.
Any particular reason as to why it fails with more number of rows? Is it something related
to the order of how iterators launch their scans?
The other tests try with few rows and single region and they all pass.
