Subject [jira] [Created] (HADOOP-8266) Backport LZ4 compression
Date Wed, 11 Apr 2012 00:07:20 GMT
Backport LZ4 compression
------------------------

                 Key: HADOOP-8266
                 URL: https://issues.apache.org/jira/browse/HADOOP-8266
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 0.23.0, 0.22.0, 0.21.0
            Reporter: Bert Sanders


LZ4 compression is currently enabled for 0.23.1 and 0.24.

However, it is not available for earlier versions of Hadoop.
As a consequence, existing distributions such as Cloudera CDH3U3 cannot benefit from it.

The request is to backport the LZ4 compression scheme up to a "reasonable level", typically
up to the first version with Snappy compression supported (0.21.0).
