Hi all，

I installed PS toolkits 3.4.2 by netinstall ISO image,  when I add a new schedule test, there is nothing for the result, I got Error retrieving test data: undefined.

And when I try to restart the services of cassandra, I got the messages as:

# service cassandra restart

Shutdown Cassandra: bash: line 0: kill: (12239) - No such process

ERROR: could not stop cassandra:  cassandra dead but pid file exists

Starting Cassandra: OK

# service cassandra status

cassandra dead but pid file exists

 

# service cassandra restart

Shutdown Cassandra: cat: /var/run/cassandra/cassandra.pid: No such file or directory

kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]

ERROR: could not stop cassandra:  cassandra dead but subsys locked

Do anybody have idea about this problem?

Best Regards,

Zhiyan Zheng
