Subject [jira] Commented: (CASSANDRA-2081) Consistency QUORUM does not work anymore (hector:Could not fullfill request on this host)
Date Tue, 01 Feb 2011 21:48:28 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12989400#comment-12989400
] 

Thibaut commented on CASSANDRA-2081:
------------------------------------

There is absolutely no load on the cluster, so it's strange that the timeout is being triggered.
I will put the other nodes into debug mode tomorrow as well and post the DEBUG output of 0.1,
0.2, and 0.3

I can access the cluster with consistency level QUORUM again, while still using apache-cassandra-2011-01-28_20-06-01.jar
and hector 7.0.25 in my application.
