Subject [jira] [Updated] (HBASE-5470) Make DataBlockEncodingTool work correctly with no native compression codecs loaded
Date Thu, 23 Feb 2012 23:35:48 GMT

     [ https://issues.apache.org/jira/browse/HBASE-5470?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhihong Yu updated HBASE-5470:
------------------------------

    Description: 
DataBlockEncodingTool was fixed as part of porting data block encoding (HBASE-4218) to 89-fb
(https://reviews.facebook.net/rHBASEEIGHTNINEFBBRANCH1245291, https://reviews.facebook.net/D1659).
The bug appeared when using GZ as baseline compression codec but not loading native Hadoop
libraries, in which case the compressor instance would be null. The purpose of this JIRA is
to bring the trunk version of DataBlockEncodingTool to parity with the 89-fb version, and
further improvements to the tool will be made separately.
