The nodetool command is now able to run successfully, however the command that is run now returns:

$ ssh automaton@10.10.10.10 -oStrictHostKeyChecking=no -A -o ConnectTimeout=2 -o ConnectionAttempts=1 -n -t '/tmp/datastax/ds-collector -L -f /tmp/datastax/collector.conf'
Pseudo-terminal will not be allocated because stdin is not a terminal.
read configuration from file: completed OK RC=0
10.10.10.10

as the script is taking 'read', 'configuration', 'from' etc. as separate node names this gives many name resolution errors:

$ ./ds-collector -f collector.conf -n 10.10.10.10 -T

So will need to add an if listNodesMode="false" to line 1056:

diagnostic-collection/ds-collector/ds-collector

Line 1056 in 0580fa4
