Subject Cassandra dying in VM
Date Tue, 23 Feb 2016 18:50:32 GMT
I'm using the latest https://github.com/vlsi/calcite-test-dataset. It
seems that Cassandra runs for a day or so (I can run Calcite's full
suite, including integration tests), then Cassandra dies (the 4
CassandraAdapterIT tests fail). When I log into the VM, Cassandra is
not available:

$ calcite-test-dataset/vm/
$ vagrant ssh
Welcome to Ubuntu 14.04.2 LTS (GNU/Linux 3.16.0-30-generic x86_64)

 * Documentation:  https://help.ubuntu.com/
Last login: Fri Feb 19 12:33:59 2016 from 10.0.2.2
vagrant$ cqlsh -k twissandra `hostname -I`
Connection error: ('Unable to connect to any servers', {'10.0.2.15':
error(111, "Tried connecting to [('10.0.2.15', 9042)]. Last error:
Connection refused")})

Restarting the service doesn't help:

vagrant$ sudo service cassandra restart
 * Restarting Cassandra cassandra
             [OK]
start-stop-daemon: warning: failed to kill 11109: No such process
vagrant$ sudo service cassandra restart
 * Restarting Cassandra cassandra
             [ OK ]
vagrant$ cqlsh -k twissandra `hostname -I`
Connection error: ('Unable to connect to any servers', {'10.0.2.15':
error(111, "Tried connecting to [('10.0.2.15', 9042)]. Last error:
Connection refused")})

Restarting the VM solves the problem.

Is anyone else seeing this? Any ideas how to fix Cassandra so that it stays up?

Julian
