Subject [jira] [Created] (HAWQ-1621) Call FileSystem.closeAllForUGI at the end of request when PXF impersonation is on
Date Thu, 31 May 2018 18:06:00 GMT
Divya Bhargov created HAWQ-1621:
-----------------------------------

             Summary: Call FileSystem.closeAllForUGI at the end of request when PXF impersonation
is on
                 Key: HAWQ-1621
                 URL: https://issues.apache.org/jira/browse/HAWQ-1621
             Project: Apache HAWQ
          Issue Type: Improvement
          Components: PXF
            Reporter: Divya Bhargov
            Assignee: Ed Espino


Due to open Hadoop JIRA: https://issues.apache.org/jira/browse/HDFS-3545 , when PXF impersonation
is on, proxy UGIs created for each request produce FileSystem cache entries that are not removed
when the request is over. This causes OutOfMemory errors since the entries are never removed.
To remove the entries and clean the cache, we should call FileSystem.closeAllForUGI at the
end of request when PXF impersonation is on.
