Subject [jira] [Commented] (HIVE-4501) HS2 memory leak - FileSystem objects in FileSystem.CACHE
Date Wed, 25 Sep 2013 20:04:02 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13778006#comment-13778006
] 

Thejas M Nair commented on HIVE-4501:
-------------------------------------

I have corrected the description to say that these variables should be set to true to disable
the cache.

[~apivovarov]
I thought you saw lease checker threads when you set the variables to false (ie cache was
not disabled).

> 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 true.
> Users should not have to bother with this extra configuration.
