[jira] [Commented] (IMPALA-5746) Remote fragments continue to hold
onto memory after stopping the coordinator daemon
[ https://issues.apache.org/jira/browse/IMPALA-5746?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17133402#comment-17133402 ]
Sahil Takiar commented on IMPALA-5746:
--------------------------------------
A WIP patch for adding a test-case for this issue was posted here: https://gerrit.cloudera.org/#/c/15666/ - note that the query in the test case is simple enough that it doesn't reproduce the issue mentioned in the previous few comments.
