Hello Folks, I'm adding another node on my 14 node open source apache cassandra 2.2.8 cluster. New node is taking long time to join the cluster. I see there are bunch of pending [memtablepostflush] threads. I did increase memtable_flush_writers from 8 to 24 , though it is not helping with situation.
Can you guys please share your experience or advise me what else I can look so
to remediate the situation.
