---------------------------------------------------------------
We had one node defined as the seed node, which was node 1.
When we turned off node 3 to update the packages, we didn't get the quorum
issue. It was only when we turned on node3 with 2.1.3 and started the sstable
upgrade did we start seeing the quorum issue.
Is it possible that node1 was unavailable since it was streaming to node 3? And
therefore only node2 was the only node available?
We also only have one seed node, node1.

> Upgrading from 2.0.9 to 2.1.3 with 3 nodes, CL = quorum causes exceptions

> Key: CASSANDRA-8917
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8917
> Project: Cassandra
> Issue Type: Bug
> Environment: C* 2.0.9, Centos 6.5, Java 1.7.0_72, spring data
> cassandra 1.1.1, cassandra java driver 2.0.9
> Reporter: Gary Ogden
> Attachments: b_output.log, jersey_error.log, node1-system.log,
> node2-system.log, node3-system.log

>
> We have java apps running on glassfish that read/write to our 3 node cluster
> running on 2.0.9.
> we have the CL set to quorum for all reads and writes.
> When we started to upgrade the first node and did the sstable upgrade on that
> node, we started getting this error on reads and writes:
> com.datastax.driver.core.exceptions.UnavailableException: Not enough replica
> available for query at consistency QUORUM (2 required but only 1 alive)
> How is that possible when we have 3 nodes total, and there was 2 that were up
> and it's saying we can't get the required CL?
