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.
