Hi I am using a zookeeper ensemble of 3 nodes running 3.4.13. Sometimes after reboot of machine zookeeper is not starting and I am seeing the below errors in logs.
I have seen https://issues.apache.org/jira/browse/ZOOKEEPER-1653 . Can someone let me if this is fixed in 3.4.13 or not as I can see the issue still open? Also can somone suggest what is the recommended way to recover the set-up ? 2019-08-19 04:18:36,906 [myid:2] - ERROR [main:QuorumPeer@692] - Unable to load database on disk java.io.IOException: The current epoch, 7, is older than the last zxid, 34359738370 at org.apache.zookeeper.server.quorum.QuorumPeer.loadDataBase(QuorumPeer.java:674) at org.apache.zookeeper.server.quorum.QuorumPeer.start(QuorumPeer.java:635) at org.apache.zookeeper.server.quorum.QuorumPeerMain.runFromConfig(QuorumPeerMain.java:170) at org.apache.zookeeper.server.quorum.QuorumPeerMain.initializeAndRun(QuorumPeerMain.java:114) at org.apache.zookeeper.server.quorum.QuorumPeerMain.main(QuorumPeerMain.java:81) 2019-08-19 04:18:36,908 [myid:2] - ERROR [main:QuorumPeerMain@92] - Unexpected exception, exiting abnormally java.lang.RuntimeException: Unable to run quorum server at org.apache.zookeeper.server.quorum.QuorumPeer.loadDataBase(QuorumPeer.java:693) at org.apache.zookeeper.server.quorum.QuorumPeer.start(QuorumPeer.java:635) at org.apache.zookeeper.server.quorum.QuorumPeerMain.runFromConfig(QuorumPeerMain.java:170) at org.apache.zookeeper.server.quorum.QuorumPeerMain.initializeAndRun(QuorumPeerMain.java:114) at org.apache.zookeeper.server.quorum.QuorumPeerMain.main(QuorumPeerMain.java:81) Caused by: java.io.IOException: The current epoch, 7, is older than the last zxid, 34359738370 at org.apache.zookeeper.server.quorum.QuorumPeer.loadDataBase(QuorumPeer.java:674) ... 4 more----
