Bootstrapping node stalls. Bootstrapper thinks it is still streaming some
sstables. The source nodes do not. Caused by IllegalStateException on source
nodes.

Key: CASSANDRA-3908
URL: https://issues.apache.org/jira/browse/CASSANDRA-3908
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.0.7
Environment: Ubuntu
Reporter: Dominic Williams
Fix For: 1.0.8
This problem looks like 2792
I am bootstrapping a new node into my cluster.
There are two keyspaces FightMyMonster and FMM_Studio. The first keyspace
successfully streams and the whole operation is probably at 99%+ when it stalls
on some sstables in the much smaller FMM_Studio keyspace.
Netstats on the bootstrapping node reports it is still streaming:
root:/var/lib/cassandra/data# nodetool -h localhost netstats
Mode: JOINING
Not sending any streams.
Streaming from: /192.168.1.9
FMM_Studio: /var/lib/cassandra/data/FMM_Studio/AuthorClasses-hc-134-Data.db
sections=1 progress=0/160 - 0%

However, running netstats on the source nodes reports they are not streaming:
root:~# nodetool -h localhost netstats
Mode: NORMAL
Nothing streaming to /192.168.1.11
Not receiving any streams.

Examination of the logs on the source nodes show an IllegalStateException that
has likely interrupted/broken the streaming process.

There are two problems:
(1) the source nodes should report to the bootstrapping node that there has
been a problem so that it may retry or giveup
(2) the IllegalStateException that breaks streaming
