Subject [jira] Updated: (CASSANDRA-1927) Hadoop Integration doesn't work when one node is down
Date Mon, 03 Jan 2011 01:19:46 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-1927?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Utku Can Topcu updated CASSANDRA-1927:
--------------------------------------

    Description: 
using the same directives in the sample code:

When I start the CFInputFormat to read a CF in a keyspace of RF=3 on a 4-node cluster:
- If all the nodes are all up, everything works fine and I don't have any problems walking
through the all data in the CF, however
- If there's a node down, the hadoop job does not even start, just dies without any errors
or exceptions.

So I'm really sorry for not being able to post any errors or exceptions, though it's really
easy to reproduce. Just startup a cluster and take one node down and you're there :)
