> Key: HAWQ-1621
> URL: https://issues.apache.org/jira/browse/HAWQ-1621
> Project: Apache HAWQ
> Issue Type: Improvement
> Components: PXF
> Reporter: Divya Bhargov
> Assignee: Alexander Denissov
> Priority: Major
> Fix For: 2.4.0.0-incubating
>
>
> 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.
