Subject [jira] [Commented] (HBASE-11860) Restore UpgradeTo in order to upgrade a HBase cluster to the latest release
Date Mon, 08 Sep 2014 23:22:31 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11860?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14126290#comment-14126290
] 

Enis Soztutar commented on HBASE-11860:
---------------------------------------

For the record, HBASE-11611 is not committed to branch-1 because we still want to support
0.94 -> 1.0 upgrade (though it is still to be tested, see HBASE-11915)

> Users should have the option to upgrade to a newer release of HBase without performing
a transitive upgrade to HBase 0.96 (EOL'd) or HBase 0.98 and then HBase 1.x or 2.x
> In HBASE-11611 UpgradeTo96 was removed and it won't be possible to migrate a HBase 0.94
cluster to HBase 1.x or 2.x  without the extra step. 
> Initially we can restore part of the functionality of the tool supporting migration to
namespaces and report for the existence of any HFileV1 file and ZKDataMigrator could be safely
removed.
