Subject HintedHandoff process does not finish
Date Fri, 27 Sep 2013 11:18:46 GMT
Hi,

One one of my nodes, the (storage) load increased dramatically (doubled),
within one or two hours. The hints column family was causing the growth. I
noticed one HintedHandoff process that was started some two hours ago, but
hadn't finished. Normally, these processes take only a few seconds, 15
seconds max, in my cluster.

The not-finishing process was handing the hints over to a host in another
data center. There were no warning or error messages in the logs, other
than the repeated "flushing high-traffic column family hints".
I'm using Cassandra 1.2.3.

   - What can be the reason for the handoff process not to finish?
   - What would be the best way to recover from this situation?
   - What can be done to prevent this from happening again?


Thanks in advance,
Tom
