Hi, On one of our server, compaction process is hanging. It's stuck at 80%. It was stuck for last 3 days. And today we did a cluster restart (one host at time). And again it is stuck at same 80%. CPU usages are 100% and there seems no IO issue. We are seeing following kinds of WARNING in system.log
*BatchStatement.java (line 226) Batch of prepared statements for [****, *****] is of size 7557, exceeding specified threshold of 5120 by 2437.* Other than this there seems no error. I have tried to stop compaction process, but it does not stop. Cassandra version is 2.1. Can someone please guide us in solving this issue? Thanks & Regards, Atul Atri.
