Server not coming up because of file corruption A server might not be able to read its database and fail to come up because of some file corruption in the transaction logs of the ZooKeeper server. You will see some IOException on loading ZooKeeper database. In such a case, make sure all the other servers in your ensemble are up and working. Use "stat" command on the command port to see if they are in good health. After you have verified that all the other servers of the ensemble are up, you can go ahead and clean the database of the corrupt server. Delete all the files in datadir/version-2 and datalogdir/version-2/. Restart the server.
