New node got stuck joining the cluster after a while

Analia Lorenzatto

Hello guys, 

I have a cluster comprised of 2 nodes, configured with vnodes.  Using 2.1.0-2 version of cassandra.

And I am facing an issue when I want to joing a new node to the cluster.

At first starting joining but then it got stuck:

UN  1x.x.x.x  348.11 GB  256     100.0%            xxxxxxxxxxxx  1c
UN  1x.x.x.x  342.74 GB  256     100.0%            xxxxxxxxxxxx  1c
UJ  1x.x.x.x  26.86 GB   256     ?                 xxxxxxxxxxxx  1c


I can see some errors on the already working nodes:

I've been checking the heap size's consumption and it does not look like getting out of memory.

I am not sure what to do to fix that problem.  Also I am not sure how to proceed If I want to re-bootstrap the new node in order to not get worse the situation.  I've been reading suggestions on the net, but I am not completely sure.

Could you please please help me with that?

Thanks in advance, any help would be appreciated!

Re: New node got stuck joining the cluster after a while

Hi,

The 2.1.x series is not recommeded for use, especially the first versions. I would downgrade to 2.0.14 or if must stay on 2.1 upgrade your cluster to 2.1.4 or the imminent release of 2.1.5.

This mailing list as a few tips how to deal with the 2.1.x releases, but the best way is indeed a downgrade or wait for the 2.1.5.

Analia Lorenzatto
Thanks very much for answering!

Do you think that after failing the joining task of a node to the cluster should I run some repairs and cleanups?  

Thanks!

I've been checking the heap size's consumption and it does not look like getting out of memory.

I am not sure what to do to fix that problem.  Also I am not sure how to proceed If I want to re-bootstrap the new node in order to not get worse the situation.  I've been reading suggestions on the net, but I am not completely sure.

Could you please please help me with that?

Thanks in advance, any help would be appreciated!
