The dsetool command stop_core_reindex is failing with connection refused

Issue:

When I issue the command:

dsetool stop_core_reindex <keyspace>.<core>

I receive an error stating connection refused.

Some dsetool commands use the same interface/port that the solr admin ui utilizes, which is 8983 by default. You can verify this with:

automaton@ip-10-101-32-78:~$ netstat -tulpn | grep -i listen

tcp6 0 0 :::61621 :::* LISTEN -
tcp6 0 0 :::22 :::* LISTEN -
tcp6 0 0 :::18080 :::* LISTEN 15244/java

In this case, the default is:

tcp 0 0 0.0.0.0:8983 0.0.0.0:* LISTEN -

However, in your environment you may have locked this down a bit, so your output could read:

tcp 0 0 172.28.219.42:8983 0.0.0.0:* LISTEN 152025/java

Solution:

If your netstat output looks similar to the above, specifying ip, then you should run the command as:

dsetool -h 172.28.219.42 stop_core_reindex <keyspace>.<core>
