Subject [jira] [Updated] (HBASE-8702) Make WALEditCodec pluggable
Date Wed, 12 Jun 2013 20:34:20 GMT

     [ https://issues.apache.org/jira/browse/HBASE-8702?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jesse Yates updated HBASE-8702:

    Attachment: hbase-8702-0.94-v1.patch

Updated patch for 0.94. Not significantly different from the other one, just a little nit

I didn't end up using ReflectionUtils since we don't have the HBase version in 0.94 and the
stuff from Hadoop looks a bit too heavy weight - sooo its back to a nullary constructor (which
you get by default anyways) and an empty init method. 

In the end, this ends up being just as easy for users to implement a WALEditCodec.

I'd like to commit tonight (assuming the tests for this pass locally).

> WALEditCode needs to be pluggable to support alternative serialziation mechanisms. 
> The open question here is whether to support the alternative codec when doing replication
- both clusters would need the codec on the classpath, which has additional overhead and also
will be a little bit complicated when making the WAL serialization backwards compatible in
> This is the follow-up to HBASE-8636.
