Subject [jira] [Created] (HADOOP-8406) CompressionCodecFactory.CODEC_PROVIDERS iteration is thread-unsafe
Date Thu, 17 May 2012 00:56:25 GMT
Todd Lipcon created HADOOP-8406:

             Summary: CompressionCodecFactory.CODEC_PROVIDERS iteration is thread-unsafe
                 Key: HADOOP-8406
                 URL: https://issues.apache.org/jira/browse/HADOOP-8406
             Project: Hadoop Common
          Issue Type: Bug
          Components: io
    Affects Versions: 2.0.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon

CompressionCodecFactory defines CODEC_PROVIDERS as:
  private static final ServiceLoader<CompressionCodec> CODEC_PROVIDERS =
but this is a lazy collection which is thread-unsafe to iterate. We either need to synchronize
when we iterate over it, or we need to materialize it during class-loading time by copying
to a non-lazy collection
