----------------------------------------
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.
