perfSONAR User Q&A and Other Discussion

["Sturm, Daniel" <>]

Because I'm not sure what exactly I'm looking for, I'll send you the output of both commands. I have already tried restarting cassandra, rebooting the webserver, and I have even tried this solution, which I had found using google search:

"over at https://issues.apache.org/jira/browse/CASSANDRA-10920

the quick fix is to add the following the cassandrea init.d file

start)
# Cassandra startup
echo -n "Starting Cassandra: "
+ pid_dir=`dirname $pid_file`
+ [ -d $pid_dir ] || install -m 755 -o $CASSANDRA_OWNR -d $pid_dir
su $CASSANDRA_OWNR -c "$CASSANDRA_PROG -p $pid_file" > $log_file 2>&1"

None of it changes that cassandra is always active (exited) in systemd.

Here are the specific responses I get from those two commands:

"[root@igswmcwmlt00010a cassandra]# systemctl restart cassandra.service

Have you run “systemctl restart cassandra”? That should bring it back since it just sounds like it stopped running. If it does not come back, do you have a stale java process (ps auxw | grep java)? or is there anything in the cassandra logs of note?

Hi Syzmon,

I have updated my toolkit a number of times. I've also checked for newer repositories, but a quick "rpm -qa | grep rc3" tells me that everything is apparently up to date. My systemctl shows cassandra.service as active (exited), and I assume I want cassandra to be active (running) so it can do database things.

Thanks for the heads up,

-Daniel

Hey, I just installed the perfsonar 4.0 release candidate ISO for centos 7, and I've been running into some trouble with Cassandra and Esmond. I searched around and made some changes, most notably from this exchange: http://perfsonar-user.internet2.narkive.com/NH9FTXDl/perfsonar-4-0-rc2-cassandra-logs-have-fatal-errors

Hi Daniel,

Did you update the toolkit after installation? ISO is a bit old and there have been many changes since that time which may fix some odd behaviour.

Best regards,
