Apache cassandra not joining cluster ring

Hello,

I've a four node apache cassandra community 1.2 cluster in single
datacenter with a seed.
All configurations are similar in cassandra.yaml file.
The following issues are faced, please help.

1] Though fourth node isn't listed in nodetool ring or status command,
system.log displayed only this node isn't communicating via gossip
protoccol with other nodes.
However both jmx & telnet port is enabled with proper listen/seed address
configured.

2] Though Opscenter is able to recognize all four nodes, the agents are not
getting installed from opscenter.
However same JVM version is installed as well as JAVA_HOME is also set in
all four nodes.

Further observed that problematic node has Ubuntu 64-Bit & other nodes are
Ubuntu 32-Bit, can it be the reason?

Thanks,
Joy

All great comments and questions, Adrian.

Joyabrata, there is also an IRC channel for help working through your 
issues, if that might help. Do camp on the channel, if someone doesn't 
answer right away.

   #cassandra on irc.freenode.net

Kind regards,
Michael

Re: Apache cassandra not joining cluster ring

Posted by Adrian Rodriguez <og...@gmail.com>.
If I were you, I would make sure all nodes were the same. The 32 / 64 thing might not be an issue, but you probably don't want that on a production cluster. What would help is if your pasted the output of all nodes for these commands:


1) echo $JAVA_HOME

2) echo $PATH

3) which java

4) java -version

5) whoami

6) ps aux | grep cassandra




And if you could answer these questions:




1) how do you start Cassandra on the first 3 nodes?




2) how do you start it on the 4th node?




3) how did you start opscenter?




I'm also a bit confused as to what your current problem is. Are you having trouble installing the opscener agents from the opscener ui?

Cool Buddy, I didn't email you directly because I didn't have it!

I didn't understand how it's polluting dev list as well?

1. It's not dev list, it's user forum where users discuss operational
issues.
2. Is discussing & requesting help pollutes a tech forum?
3. In this way the resolution will also be shared among all.

Also please send email individually onwards if you've any personal advice.

Thanks in anticipation,
Joy

Re: Apache cassandra not joining cluster ring

Posted by Joyabrata Das <jo...@gmail.com>.
After explicitly enabling port
9160 (Cassandra client port (Thrift)) in that particular node it's
connected to ring however other nodes are working with same configuration.

Now Opscenter is installed in that particular node after explicitly enabling
61620 (OpsCenter monitoring port), 61621 (OpsCenter agent port) in all
nodes though in other nodes error is displaying while installing from GUI as

"Unable to find a java executable! Please install java or set JAVA_HOME.
Exit code: 4".

Though java is installed & JAVA_HOME is also set for all users.
$ echo $JAVA_HOME

/app/jdk1.6.0_16

Please help!

This may not be recommended, might/should(?) work, and may be a reason 
[0]. My first suggestion would be to remove this variable. This would 
also give you a chance to go through the steps of adding a new node to 
the cluster again [1] - you might stumble on something.

Hello

   The nodetool status that you mentioned, was that executed on the 4th
node itself?   Also What does netstat display?  Are the correct ports
listening on that node?

   Per opscenter, What version of opscenter are you using?  Are you able to
manually start the agents on the nodes themselves?

Re: Apache cassandra not joining cluster ring

Posted by Michael Shuler <mi...@pbandjelly.org>.
As Jonathan also asked for some various details, perhaps it would be 
helpful to be very specific about who, what, when, where, why, what you 
tried, actual errors, versions, pastebins of configs, etc. Provide the 
things that might be needed for people to help you out.

For instance, the statement that "All configurations are similar in 
cassandra.yaml" means nothing to anyone on the list, if they can't see 
them to tell you, "oh, here on line XX, you have blah, and it should be 
blarg."
