[jira] [Updated] (HBASE-8211) Support for NN HA for 0.94

     [ https://issues.apache.org/jira/browse/HBASE-8211?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Himanshu Vashishtha updated HBASE-8211:
---------------------------------------

    Attachment: HBase-8211-v1.patch

patch for 0.94. Running a jenkins job now. The last jenkins job has one failure, which is fixed. Ran the patched version on a local set up (with hdfs running). Restarted the nn with some delay, and rs remains good. 
I left out some standalone tools (hbck, compactionTool, regionsplitter) from this change. Snapshot is also not touched, as it is resilent to failures (from a rs point of view).
Please review.

> HBase-8156 is for adding support for retrying non-idempotent operations. This is useful in case NN is suffering from n/w hiccups, etc. This jira is to add similar support for 0.94.x branch.
