5000 uncompacted sstables is unusual. did you disable compaction during your inserts? that is dangerous. > during the compaciton process ,something wrong with one of the 10 nodes , > when the size of the compacted temp file rech nearly 100GB( before > compaction ,the size is ~240G) sounds like it just didn't have enough memory to compact 5000 sstables at once. not very surprising. a better approach: let it perform minor compactions normally, and when it is done with that (no compaction in progress and compactionmanager.pendingtasks == 0), then issue the major compaction if you still want to. -- Jonathan Ellis Project Chair, Apache Cassandra co-founder of Riptano, the source for professional Cassandra support http://riptano.com
