Thanks Jonathan. I added an extra directory big enough and at least the
bootstrap worked.
However, it brings me to questions that i cant seem to find an answer to.
In my case, i had a 2 node cluster to start with, replication factor of 2,
basically all data residing on both machines. Both nodes h
And having said all that: Azure Table storage model doesn't look like
Cassandra. There is a schema, there are partition keys. It more
resembles something like VoltDB than the map of maps (of maps) of
Cassandra (and BigTable, and HBase).

I encounter the same problem with you,and I replace

You can't build Cassandra against trunk thrift, the API has changed.
Stick to the one shipped w/ Cassandra and you will be fine.

it looks to me like you are describing "compaction causes a lot of
i/o." see http://wiki.apache.org/cassandra/MemtableSSTable#Compaction
things you can do about the extra i/o:

by 10x or so)
- reduce compaction priority (see

if you have a data directory defined with enough room, Cassandra will

Have you looked into Amazon's EC2? That's worked quite well for us.
I haven't looked into other alternatives enough to know how it would
compare for a 24/7 "production" application, but Amazon's "pay as you go"
