Thejas M Nair commented on HIVE-4501:
-------------------------------------
It would better to call shim.closeAllForUGI to free up the FileSystem objects,
like it is done for the kerberos mode from HiveSessionImplwithUGI.close().
Calling shim.closeAllForUGI at end of TUGIContainingProcessor.process is too
early and ends up returning empty results for the queries.
> HS2 memory leak - FileSystem objects in FileSystem.CACHE

> Key: HIVE-4501
> URL: https://issues.apache.org/jira/browse/HIVE-4501
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 0.11.0
> Reporter: Thejas M Nair
>
> org.apache.hadoop.fs.FileSystem objects are getting accumulated in
> FileSystem.CACHE, with HS2 in unsecure mode.
> As a workaround, it is possible to set fs.hdfs.impl.disable.cache and
> fs.file.impl.disable.cache to false.
> Users should not have to bother with this extra configuration.
