hi,

sometimes we have the problem that we have hinted handoffs (for example
because auf network problems between 2 DCs) that do not get processed
even if the connection problem between the dcs recovers. Some of the
files stay in the hints directory until we restart the node that
contains the hints.

after the restart of cassandra we can see the proper messages for the
hints handling

Apr 11 09:28:56 bigd006 cassandra: INFO  07:28:56 Deleted hint file
c429ad19-ee9f-4b5a-abcd-1da1516d1003-1491895717182-1.hints
Apr 11 09:28:56 bigd006 cassandra: INFO  07:28:56 Finished hinted
handoff of file c429ad19-ee9f-4b5a-abcd-1da1516d1003-1491895717182-
1.hints to endpoint c429ad19-ee9f-4b5a-abcd-1da1516d1003

is there a way (for example via jmx) to force a node to process
outstanding hints instead of restarting the node?
does anyone know whats the cause for not retrying to process those
hints automatically?

br,
roland
