I fixed the new allocation algorithm in non bootstrap case,
https://issues.apache.org/jira/browse/CASSANDRA-13080?filter=-2, the fix is

You should run “primary range” repairs on all nodes. That will go a lot faster
than full repair. In C* 2x you can do this in parallel.. you can determine how
many you can run at the same time.. basically how much pressure you can put on
ur system.

Thanks, that
Hi Karthick, repairs can be tricky.
You can (and probably should) run repairs as apart of routine maintenance. And
of course absolutely if you lose a node in a bad way. If you decommission a
node for example, no “extra” repair needed.
If you are using TWCS you should probably not run repai
Hiya,
We have our Cassandra 2.1 cluster being monitored by checking the JMX
on the org.apache.cassandra.metrics type=ThreadPools bean
We've got a threshold of 15 for warnings as per

Periodically I have been running Full repair process befor GC Grace period
as mentioned in the best practices.Initially, all went well but as the data
size increases Repair duration has increased drastically and we are also
facing Query timeouts during that time and we have tried incremental repair
Hello,
In the process of upgrading our cluster from 2.1 to 2.2 we have triggered
the SSTable rewriting process like this:
$ nodetool upgradesstables -j 4 # concurrent_compactors=5
Then if we would immediately check the compactionstats, we see that 4
compactions of type 'Upgrade sstables' are ru
