Karthik Kambatla commented on HADOOP-9401:
------------------------------------------
The patch now has only two methods for returning the count of leased
compressors/decompressors. While we can create a single info bean to return the
properties, now that we have only 2 properties, thought it should be okay to
have just two methods.
Kicking off Jenkins to see if there are any issues.
> 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
> Attachments: hadoop-9401.patch, hadoop-9401.patch

> 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.
