Subject java.io.IOException: FAILED_TO_UNCOMPRESS(5) exception when running nodetool rebuild
Date Tue, 19 Mar 2013 16:51:02 GMT
Hi all,

I am running into strange error when bootstrapping Cassandra cluster
in multiple datacenter setup.

The setup is as follows: 3 nodes in AWS east, 3 nodes somewhere on
Rackspace/Openstack. I use my own snitch based on EC2MultiRegionSnitch
(it just adds some ec2 avalability zone parsing capabilities). Nodes
in the cluster connect to each other and all seems ok.

When I start the Rackspace cluster first, populate it with data and
then let the AWS cluster bootstrap from it, it works great. However
the other way round it just breaks.

The breakage demonstrates as follows:

- nodetool rebuild us-east command hangs
- cassandra's log contains the following:

        ... 1 more

- the SSTable file is not downloaded.

To make it even more confusing, when I tried just one node in AWS and
one on Rackspace, the rebuild ran well. Also for two nodes. Only with
three on AWS side the process failed.

It's cassandra 1.2.1 running on

java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.8) (rhel-1.56.1.11.8.el6_3-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

SSL is configured for inter-DC communication.

Any hints?

regards,

Ondrej Cernos
