Subject [jira] Created: (HDFS-1279) FsShell have resource leak
Date Fri, 02 Jul 2010 09:03:49 GMT
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.
