Unable to start zookeeper

I went through full disk space(100%) issue due to which core got corrupted. As I have googled I have removed all snapshots from version-2 and datalog/version-2.

Right now /var/zookeeper having only myid file and __backup folder.

While I am trying to start zookeeper I am getting below error

2016-06-12 12:43:36,512 [myid:4] - ERROR [main:FileTxnSnapLog@210] - Parent /search/cluster1/overseer/queue missing for /search/cluster1/overseer/queue/qn-0000000288

Apparently your zookeeper seems to be in an inconsistent state where it's trying to find a missing node. Look in the zoo.cfg file to see if your ZooKeeper's dataDir setting are consistent.

Or this could be a know issue of Zookeeper. https://issues.apache.org/jira/browse/ZOOKEEPER-1813
