Subject [jira] [Updated] (DRILL-2757) Verify sort spill and other operators correctly handle low memory conditions and cancellations
Date Fri, 10 Apr 2015 20:38:13 GMT

     [ https://issues.apache.org/jira/browse/DRILL-2757?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Westin updated DRILL-2757:
--------------------------------
    Description: 
Check that the path through sort that notices low memory conditions and causes the sort to
spill ("out of memory condition management").

Also check to make sure we handle queries and fragment failures properly under these conditions.

"hashjoin, hashagg, and topn use large amounts of memory,and may be unable to
complete if their memory needs can't be met; for all others, the idea is that they can complete
if they get their reservation"
