I am using org.apache.zookeeper.server.SnapshotFormatter to dump out the
content of a snapshot (908M) and got this exception:
Exception in thread "main" java.io.EOFException

Is there any debug mode I can turn on (in SnapshotFormatter) to find out what
happened?
Background: a standalone Zookeeper failed on restart with below exception. I
tried to see what is being stored from the last snapshot.
