Hector Problem Basic one
Hi Every One,
Actually I was using cassandra long time back and when i tried today, I am
getting a problem from eclipse. When i am trying to run a basic hector
(java) example, I am getting an exception
me.prettyprint.hector.api.exceptions.HectorException: All host pools marked
down. Retry burden pushed out to client. . But My server is up. Node tool
also whows that it is up. I donno what happens..
1.)Is it any thing to do with JMX port.
2.) What is the storage port in casandra.yaml and jmx port in
cassandra-env.sh

Hi, Hector does not retry on a down server. In the unit tests where you have
just one server, Hector will pass the exception to the client.
Can you tell us please what your test looks like ?

I only saw this error message when all Cassandra nodes are down.
How you get the Cluster and how you set the hosts?

We had this one, even tho in the hector documentation it says that it
retry s failed servers even 30 by default, it doesn't.
Once we explicitly set it to X seconds, when ever there is a failure,
ie with network (AWS), it will retry and add it back into the pool.

Hey,
We had this one, even tho in the hector documentation it says that it
retry s failed servers even 30 by default, it doesn't.
Once we explicitly set it to X seconds, when ever there is a failure,
ie with network (AWS), it will retry and add it back into the pool.
