Cassandra: Command Not Found

Question

I am currently working on the Cassandra tutorials about data modeling. I cannot understand why whenever I try to run the cassandra service from the bin folder I receive the error:

"Cassandra: command not found".

The same happens if I try to run nodetool, or cqlsh utilities. Can anybody help me to resolve the problem?

Answer 1

All the cassandra binary are in the $CASSANDRA_HOME/bin folder.

If you run command from the CASSANDRA_HOME then use :

bin/cassandra
bin/cqlsh
bin/nodetool

I had to use: sudo sh cqlsh in $CASSANDRA_HOME/bin – Fiscal

Did you try with sudo $CASSANDRA_HOME/bin/cqlsh ? – Solipsism

Answer 2

I know is too late now, but for anyone experiencing this problem, while you are already in the bin directory, use ./cqlsh < IP >. Also if you configured a multi node cluster, use ./nodetool status and check if you have all the IPs there.

Answer 4

You should go first on your Cassandra installation location or folder. / bin/

Then try to run below command:-

bin/cassandra or bin/cassandra -f

But if you have done package installation then you should try below command:- sudo service cassandra start

Please go through below link for more details about all other way to start Cassandra. https://cassandra.apache.org/doc/latest/getting_started/installing.html#installing-the-binary-tarball
