FsShell have resource leak
--------------------------
Key: HDFS-1279
URL: https://issues.apache.org/jira/browse/HDFS-1279
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs client
Affects Versions: 0.20.2, 0.20.1, 0.20-append, 0.20.3, 0.21.0
Reporter: Vladimir Klimontovich
Fix For: 0.20-append, 0.20.3, 0.21.0, 0.22.0
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.
