Make the call to cassandra.describe_keyspace fault tolerant about hector

[hz]

I don't know how to merge my modifications to my fork. I pasted my solution into gist.github.com/hz, 360995 is a interface, 360996 is request featured with failover and pooling. 360997 is the wrapper for thrift api. 30999 is the revised keyspaceimpl. you do some tricks on getColumn. I can not solve it.
After the clean wrapper of thrift api, this issue will be solved.

Sorry, it's pretty hard to see diffs in gists. It's preferable that you push back to your hz/hector repo so I can see diffs and send line comments, but if this isn't working for you, then email me a patch

Any idea when this problem is likely to be resolved? Occasionally I experience a transport error which causes the call to getKeyspace to fail. When this happens Hector does not recover and all subsequent calls to getKeyspace fail.

I guess I was just waiting for someone to need this bad enough to implement that...
If you're not into hacking that I'll try to find some time for it this week

Well, http://github.com/Mishail/hector/commit/a8c9a0accd49d1e8f76ad15d8250f608f8a9d755

Though I'm not sure that all is done properly... The code is mostly borrowed from CassandraClusterImpl. And all unit-test are passed (except one, which I marked as @ignore and specified the reason)

fixed on master e5f29a4..1bf8ab5 master -> master
