Re: truncate command fails

2012-02-08 Thread aaron morton 
truncate will throw Unavailable when it times out waiting for one of the nodes 
to return. 

The full error for the UnavailableException should include some text saying how 
many messages it received. 

You can also check the logs on the other machines to see if they are erroring. 

Finally turn up the log to DEBUG on the node you are running the truncate on 
and watch for log lines from the MessagingService  . 

Cheers

truncate command fails

2012-02-07 Thread Patrik Modesto 
Hi,

I've a strange problem with my test cluster. Calling truncate on a
small ColumnFamily on idle cluster of 4 nodes returns
UnavailableException after 10s. That 10s is set in rpc_timeout_in_ms.

All nodes are up and running, here is nodetool ring:

Address DC  RackStatus State   Load

What may be the problem?

Make sure you have JNA, without it the cost of forking ln to snapshot
is expensive.
