Enis Soztutar created HBASE-16189:
-------------------------------------
Summary: [Rolling Upgrade] 2.0 hfiles cannot be opened by 1.x
servers
Key: HBASE-16189
URL: https://issues.apache.org/jira/browse/HBASE-16189
Project: HBase
Issue Type: Sub-task
Reporter: Enis Soztutar
Priority: Critical
Fix For: 2.0.0
HBASE-10800 added MetaCellComparator, which gets written to the HFile. 1.x code
does not have the new class, hence fails to open the regions. I did not check
whether this is only for meta or for regular tables as well.
