Sent so early...
Another exception I am getting frequently with zookeeper which is a
bigger problem.
ACCUMULO-3336 <https://issues.apache.org/jira/browse/ACCUMULO-3336> says
it is unresolved yet
Saw (possibly) transient exception communicating with ZooKeeper
org.apache.zookeeper.KeeperException$ConnectionLossException:
KeeperErrorCode = ConnectionLoss for

And the worst case is whenever a zookeeper goes down cluster becomes
unreacheble for the time being, untill it restarts ingest process halts.
What do you suggest, I need to resolve these problems. I do not want to
be the ingest process to stop ever.
Thanks

ACCUMULO-2420 <https://issues.apache.org/jira/browse/ACCUMULO-2420> says that
this exception comes when a client closes a connection before scan completes. But the
connection is not closed every thread uses a common connection object to ingest and
query, then what could cause this exception?
