[jira] [Commented] (SPARK-14261) Memory leak in Spark Thrift Server

["tianshuang (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-14261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17567787#comment-17567787 ] 

tianshuang commented on SPARK-14261:
------------------------------------

The memory usage problem of java.io.DeleteOnExitHook still exists. There seems to be no good fix. After ThriftServer runs for several months, java.io.DeleteOnExitHook#files will occupy a lot of memory.

> I am running Spark Thrift server on Windows Server 2012. The Spark Thrift server is launched as Yarn client mode. Its memory usage is increased gradually with the queries in.  I am wondering there is memory leak in Spark Thrift server.
