Himanshu Vashishtha updated HBASE-2611:
---------------------------------------
Attachment: HBASE-2611-v2.patch
Patch that provides an alternative way to copy the znodes in an atomic way,
using Zookeeper multi.
It is configurable using "hbase.zookeeper.useMulti" property. It does a 'ls' on
the znode and creates Operations to do the "move" (Create new and delete old)
znodes. I tested it on a 3 node cluster and killed the server that had 200 log
znodes. The other two regionserver competed and one took away the all the
znodes. Ran TestReplication#queueFailover on a jenkins it passed.
> Handle RS that fails while processing the failure of another one
