Hey Vivek,
The same thing happened to me the other day. You may be missing a component in
your compound key.
See this thread:

Did you use the "--cql3" option with the cqlsh command?

Hello.
In the process of trying to streamline and provide better reporting
for various data storage systems, I've realized that although we're
verifying that nodetool repair runs, we're not verifying that it is
successful.
I found a bug relating to the exit code for nodetool repair, where, in

I did wait for atleast 5 minutes before terminating it. Also sometimes it
results in server crash as well, though data volume is not very huge.

The problem was - I calculated 3 tokens for random partitioner but
used them with BOP, so nodes were not supposed to be loaded evenly.
That's ok, I got it.
But what I don't understand, why nodetool ring shows equal ownership.
This is an example:
I created small cluster with BOP and three tokens

Cool.
Just keep an eye out for how big the lucene token row gets.

There is a potential issue.
You want to make sure the tombstones are distributed to all replicas *before*

replicas compact and purge their tombs

Hi!
In the last 3 days I see many messages of "READ messages dropped in last

I see no errors in the log.
There are also messages of "Finished hinted handoff of 0 rows to endpoint"
but I had those for a while now, so I don't know if they are related.

Are there any errors in server logs ?
When you do a get by secondary index at a CL higher than ONE ever RFth node is
involved.
This is an issue with using the BOP.
If you are just starting out stick with the Random Partitioner.

Not sure why you have two different definitions for the bars2 CF.
You will need to create SSTable's that match the schema cassandra has.

I'm attempting to plot how "busy" the node is doing compactions but there
seems to only be a few metrics reported that might be suitable:
