Subject [jira] [Created] (HADOOP-9401) CodecPool: Add counters for number of (de)compressors created
Date Wed, 13 Mar 2013 00:55:13 GMT
Karthik Kambatla created HADOOP-9401:

             Summary: CodecPool: Add counters for number of (de)compressors created
                 Key: HADOOP-9401
                 URL: https://issues.apache.org/jira/browse/HADOOP-9401
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 2.0.3-alpha
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla

CodecPool enables reusing compressors/decompressors created. However, the onus is on the user
to return the compressors/decompressors to the pool, and can be easily missed.

It would be quite handy to keep track of the total number of compressors/decompressors created
and helper methods to check outstanding (not returned) compressors/decompressors. It immediately
allows Hadoop and downstream projects to write unit tests for the same.
