Thanks for the reply Erik. I ran nc -l 59027 on the supervisor host, but i
think it is able to connect successfully. i ran the strace in any case and
the output is attached in the file. I ran a couple of other commands as
well and this is what i found.
*With the supervisor running*
nc -v devctsl001 59027
nc: connect to devctsl001 port 59027 (tcp) failed: Connection refused
telnet devctsl001 59027
Trying 45.32.96.34...
telnet: connect to address xx.xx.xx.xx: Connection refused
nc -l 59027
{No address already in use error. Connection seems to be open}
*With the UI running ( the storm ui connects on 59031. The UI comes up
successfully without any issues)*
nc -v devctsl001 59031
Connection to devctsl001 59031 port [tcp/*] succeeded!
telnet devctsl001 59031
Trying xx.xx.xx.xx...
Connected to devctsl001.
Escape character is '^]'.
nc -l 59031
nc: Address already in use
Might be a red herring, but thought i'd share what i have done so far.
Best,
Arjun
