I see. That helps. However, even as warnings, these go on seemingly
endlessly. Why do they not get fixed by themselves? What are we doing wrong
here?

Hi Nitay,
This is not an error but should be a warning. I have opened up a jira for
it.
http://issues.apache.org/jira/browse/ZOOKEEPER-428
The message just says that a client is connecting to a server that is
behind
that a server is was connected to earlier. The log should be warn and not
error and should be fixed in the next release.

Hey guys,
We are getting a lot of messages like this in HBase:

For more context, the block it usually appears in is:

Thanks,
