Subject [jira] [Updated] (HBASE-6052) Convert .META. and -ROOT- content to pb
Date Thu, 23 Aug 2012 20:36:42 GMT

     [ https://issues.apache.org/jira/browse/HBASE-6052?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Enis Soztutar updated HBASE-6052:

    Release Note: 
Changed .META. and ROOT tables' content to be Protobuf serialization of HRegionInfo's instead
of Writable serialization. When upgrading from 0.92 and 0.94 clusters, after master deploys
META and ROOT, and before it deploys user level tables, it does a migration for the data in
the catalog files, rewriting them in the new format. 
Before upgrading, you can take an export of the catalog tables using HBASE-3271 for backup.
