----------------------------------------------------------------------------------------------------
Key: CASSANDRA-3109
URL: https://issues.apache.org/jira/browse/CASSANDRA-3109
Project: Cassandra
Issue Type: Bug
Components: Tools
Affects Versions: 0.7.4
Environment: Centos 5.5
Reporter: Sunil Kumar
Hi all,
I have two node cassandra cluster initial replication factor for this cluster
is 1. When i changed replication factor to 2 on this live cluster.From
cassandra wiki(http://wiki.apache.org/cassandra/Operations#Replication) it is
recommended to run nodetool repair command on each node of the cluster. But
when i run nodetool command on both node disk usage on the both node got
increased to 50 times of the initial disk usage. Initially in my cluster data
with one replication factor was 1 GB on each node now its 50GB on each node and
still nodetool process is going on. Can any body help me in this problem or is
it desired behavior of cassandra???
