Subject Restarting servers
Date Fri, 12 Aug 2011 18:59:07 GMT
So restarting cassandra servers has a tendency to cause a lot of exceptions
like "MaximumRetryException: Retried 6 times. Last failure was
UnavailableException()" and "TApplicationException: Internal error
processing batch_mutate" (using pycassa).  If I restart the servers too
quickly, I get "all servers unavailable".  So two questions:

1.  Is there anything I can do to prevent MaximumRetryExceptions and
TApplicationExceptions, or is this just a case of needing better exception
2.  Are there any rules of thumb regarding how much time I should allow
between server restarts?
