Hadoop is successfully running in distributed mode.
Getting following error while starting HBase in distributed mode.
Tried everything in hbase-site.xml configuration. No idea how to proceed with the problem?

Check zoo.cfg and /etc/hosts to make sure that all zookeeper servers are reachable by the HBase master.

The pertinent pieces of information from your provided error are:-
JMSWMQ0018: Failed to connect to queue manager 'RQACBRKB'
with connection mode 'Client' and host name '172.11.11.11(6912)'.
com.ibm.mq.jmqi.JmqiException: CC=2;RC=2538;
MQRC 2538 is MQRC_HOST_NOT_AVAILABLE which is explained in Knowledge Center. In there it mentions the most common reasons for this error:-
The listener has not been started on the remote system. (please check that your listener is running on port 6912 on the machine at IP address 172.11.11.11)
The connection name in the client channel definition is incorrect. (the connection name your client is using is '172.11.11.11(6912)' - is this correct?)
The network is currently unavailable.
A firewall blocking the port, or protocol-specific traffic.
The security call initializing the IBM MQ client is blocked by a security exit on the SVRCONN channel at the server.
"java.net.ConnectException: Connection timed out: connect" usually occurs when you have a config issue or you are unable to connect to the remote server. As mentioned above do you have an error on the MQ end and if not have you checked the connection properties within config. If these are correct, are you able to reach MQ from another client, such as SOAPUI?
Can you also post the connector and flow details?
We have started using Apache Ignite and we are using TCP-communication. What we are seeing is that the clients are opening a port for communication just like the server.
My first assumption was that we don't need to open up from the server to the client, everything seemed to be working fine. However, in some cases when the topology is changing we got stack traces in the logs that indicates that the server is initiating communication with the client on this port and fails.
My question is why is the server trying to communicate directly with the client? Do we need to let the servers communicate with the client or can we simply ignore the error messages?
Below is an example of the stack trace:

Client nodes are different from server nodes mostly by the fact that they don't hold cache data and don't execute computations.
Other than that, client nodes are first-class cluster citizens and participate in communications the same way as servers do. So yes, they need to accept connections.
See https://apacheignite.readme.io/docs/clients-vs-servers
I am trying to get drill running on a 3 node cluster made up of ec2 instances. I configured
the drill-override.conf file so that it can connect to my zookeeper cluster. and then started
drillbit.sh on all three nodes, checked the status, and they were running. I try to open drill
using drill-conf and the first time it works and I ensure it can see all three drillbits
by using:
SELECT * FROM sys.drillbits;
and it shows all three drillbits properly. However, I reboot the cluster and try to retry to process
and this is the error that I get:
[ec2-user#ip-<private IP> bin]$ ./drill-conf

I've looked this up in a few places and tried out their solutions one of which was making sure
/etc/hosts is configured properly and that didn't fix it. Is there anything else I can try to solve the
issue?
Found the solution:
Had to make sure my security group for the ec2 instaqnces were configured properly by letting in the correct traffic to port 31010.

This is a bug that has been reported here https://github.com/spring-projects/spring-session/issues/150
In my case I was running embedded redis-server on port 1337 and this port was locked and went into a loop sometime back when I was running my testcases in debug mode. After that I also started spring-boot app which created another server connection on the port 6379. But I failed to terminate the server running on the port 1337. Since then I had been getting the exception when I was trying to execute test cases "Can't start redis server. Check logs for details.", since 1337 was locked. Debugging line-my-line "AbstractRedisInstance" class and "awaitRedisServerReady" method revealed "1337 Already in use" which was never logged at all. Killed this port and re-run testcases and again I was on fly. Hope this helps
