failover exception with hector
hi folks,
Just switched from C++ interface to hector, found an exception when testing with a 2-node cluster:
Exception in thread "main" org.apache.thrift.TException: Unable to failover to next host
at me.prettyprint.cassandra.service.KeyspaceImpl.skipToNextHost(KeyspaceImpl.java:598)
at me.prettyprint.cassandra.service.KeyspaceImpl.operateWithFailover(KeyspaceImpl.java:668)
at me.prettyprint.cassandra.service.KeyspaceImpl.insert(KeyspaceImpl.java:270)
at me.prettyprint.cassandra.service.ExampleClient.insertFromDB(ExampleClient.java:108)
at me.prettyprint.cassandra.service.ExampleClient.main(ExampleClient.java:45)
I was doing a lot of insertion. Probably inserting to 1 node wsa failed, and hector failed to find the other node.
I'm using cassandra-0.5.0. In conf/storage-conf.xml, the ListenAddress is configured as the IP and ThriftAddress
is left blank.
Any ideas?
cheers,
Cao Jiguang

let's continue this offline. user@ to bcc
Would be helpful if:
- You cancheck with jconsole how hector sees the ring: connect to the java
client running hector and check me.prettyprint.hector if the list of known
hosts is consistent with your setup?
- Send all recent log lines so I have better understanding why this i
happening.

Ran,
I ran the nodeprobe tool , and got the correct ring infomation.

主题: Re: failover exception with hector
I seems the host you were connected to was unable to locate the other host in the ring. That's probably a configuration error.
Can you run nodeprobe -host1 ring
where host1 is the host hector was connected to initially?
If not that, can you check with jconsole how hector sees the ring: connect to the java client running hector and check me.prettyprint.hector if the list of known hosts is consistent with your setup?
