Subject [jira] [Commented] (HADOOP-6848) FsShell have resource leak
Date Mon, 26 Nov 2012 20:22:59 GMT

Chad Rhyner commented on HADOOP-6848:
-------------------------------------

This issue has been fixed in 0.21 and beyond, and was only relevant for the 0.20.x branch.
 Since the 0.20.x branches are not on the RoadMap anymore, and there are no plans to release
another 0.20.x version, I suggest that this gets moved to WontFix.

> When FsShell exectutes -text command it's using TextRecordInputStream. This class doesn't
close inbuf and outbuf (with underlying socket in case of HDFS fs) opened in constructor.
It's ok in "classic" "command per JVM" case when -text command is being used from command-line.
But when FsShell is being used in same JVM several times (for example via http://martiansoftware.com/nailgun/index.html
project) it cause socket leak.
