Subject Re: Truncate failing with 1.0 client against 0.7 cluster
Date Wed, 18 Jul 2012 03:36:23 GMT
truncate requires all all nodes to be available. 

Let us know when you have the full error.

with one, and any and it made no difference.

fail as they get UnavailableExceptions when trying to truncate the test column families. 
This is new behaviour with the 1.0 client libraries, it doesn't happen with the 0.7 libraries.

I seem to be able to get around it if i only tell Hector about one of the nodes (we have 4).
If I give it all four then it throws the UnavailableException.
