Subject [jira] [Updated] (CASSANDRA-8917) Upgrading from 2.0.9 to 2.1.3 with 3 nodes, CL = quorum causes exceptions
Date Thu, 05 Mar 2015 15:26:41 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-8917?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gary Ogden updated CASSANDRA-8917:
----------------------------------
    Attachment: node3-system.log
                node2-system.log
                node1-system.log
                jersey_error.log
                b_output.log

b_output and jersey_error are the stacktrace errors from glassfish.

The other 3 files are from each of the 3 nodes during the time period of the upgrade and rollback
to 2.0.9.

node 3 was the node we were attempting the upgrade on (10.6.71.198 in the logs)

>             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?
