Subject [jira] [Commented] (HBASE-6226) move DataBlockEncoding and related classes to hbase-common module
Date Fri, 22 Jun 2012 18:46:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13399505#comment-13399505

Mikhail Bautin commented on HBASE-6226:
---------------------------------------

Data block encoding is a server-side feature, so putting it in hbase-common will make it available
to clients, right? What is the desired dependency graph between hbase-server, hbase-common,
and hbase-<data_block_encodingX> components?

> In order to isolate the implementation details of HBASE-4676 (PrefixTrie encoding) and
other DataBlockEncoders by putting them in modules, this pulls up the DataBlockEncoding related
interfaces into hbase-common.
> No tests are moved in this patch.  The only notable change was trimming a few dependencies
on HFileBlock which adds dependencies to much of the regionserver.
> The test suite passes locally for me.
> I tried to keep it as simple as possible... let me know if there are any concerns.
