Hi,
I have an issue in my environment running with cassandra 2.0.5, It is build
with 9 nodes, with 3 nodes in each datacenter. After loading the data, I am
able to do token range lookup or list in cassandra-cli, but when I do get
xxxxx[rowkey], the system hangs. Similar query in CQL also has same
behavior.
I have 3 nodes in the source environment, which is configured as 3
datacenter, having 1 node. I did an export from source environment and
imported into new environment with 9 nodes. The other difference is source
is configured as 256 vnodes and destination environment is with 32 vnodes.
Below is the exception i see in cassandra.
