Subject [jira] [Created] (HBASE-11860) Restore UpgradeTo in order to upgrade a HBase cluster to the latest release

Esteban Gutierrez created HBASE-11860:
-----------------------------------------

             Summary: Restore UpgradeTo in order to upgrade a HBase cluster to the latest
release
                 Key: HBASE-11860
                 URL: https://issues.apache.org/jira/browse/HBASE-11860
             Project: HBase
          Issue Type: Improvement
          Components: HFile, master
            Reporter: Esteban Gutierrez
            Assignee: Esteban Gutierrez
             Fix For: 0.99.0, 2.0.0


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.
