Hello,
thanks a lot!
The solution proposed by Gerard works perfectly.
This is the snippet of what I have done:
echo "Checking if Cassandra is up and running ..."
# Try to connect on Cassandra's JMX port 7199
nc -z localhost 7199
nc_return=$?
# Try to connect on Cassandra CQL
Hello,
thanks to everyone for the fast replies!
Unfortunately, since yesterday afternoon I have been assigned to a more
urgent task, so I will implement the solutions you proposed in the spare
time and I will let you know the outcomes asap (hopefully in few weeks).
Thanks a lot again!
Best
I did something like this in Perl. What you want to know is will the server
respond to CQL, then it is ready to use.
The Bash equivalent of what I did would be to use:
cqlsh < /dev/null
if $?
...

Hi Giovanni,
You could use netcat (nc) to test that the cassandra port is up and use a
timeout to decide when to take an action
nc -z localhost 9160
check for the exit code to decide what action to take.

Hello Gerard,
thanks for your reply.
It seems nodetool works only when the cluster is up and running.
In case of a bad startup of Cassandra, if I run "nodetool status" I get
one of these 2 errors:
1) error: No nodes present in the cluster. Has this node finished
starting up?

(Hit enter too fast)
In particular, `nodetool status` will give you a summary of the status of
the cluster. See the documentation for the parameters it takes.
-kr, Gerard.

Hello,
I would gladly welcome the help of the community on the following issue
I am having while starting Cassandra.
I am starting Cassandra by a Bash script in this way:
- $CASSANDRA_HOME/bin/cassandra -p $CASSANDRA_PID_FILE
and then, I submit some updates via
- $CASSANDRA_HOME/bin/cqlsh -f
