Subject CRC check failed
Date Thu, 13 Aug 2015 16:27:39 GMT
Hello,

Does anybody know how those "CRC check failed" errors can occur?

Apparently the data has been corrupted, what would be the most likely
scenario for this to happen?

java.io.IOException: CRC check failed
at
org.apache.zookeeper.server.persistence.FileTxnLog$FileTxnIterator.next(FileTxnLog.java:612)

org.apache.zookeeper.server.ZooKeeperServerMain.initializeAndRun(ZooKeeperServerMain.java:86)

org.apache.zookeeper.server.ZooKeeperServerMain.main(ZooKeeperServerMain.java:52)


As a result my ZK can't be started, is it recoverable?

Thanks,
Ben
