Carl Yeksigian commented on CASSANDRA-10829: -------------------------------------------- We need to ensure we only {{unmarkCompacting}} the sstables which we haven't already unmarked, otherwise we could be running a different compaction operation on the previously unmarked sstables and unmark it again after this operation is finished. > cleanup + repair generates a lot of logs > ---------------------------------------- > > Key: CASSANDRA-10829 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10829 > Project: Cassandra > Issue Type: Bug > Environment: 5 nodes on Cassandra 2.1.11 (on Debian) > Reporter: Fabien Rousseau > Assignee: Marcus Eriksson > Fix For: 2.1.x > > > One of our node generates a lot of cassandra logs (int the 10 MB/s) and CPU > usage has increased (by a factor 2-3). > This was most probably triggered by a "nodetool snapshot" while a cleanup was > already running on this node. > An example of those logs: > 2015-12-08 09:15:17,794 INFO > [ValidationExecutor:689]ColumnFamilyStore.java:1923 Spinning trying to > capture released readers [...] > 2015-12-08 09:15:17,794 INFO > [ValidationExecutor:689]ColumnFamilyStore.java:1924 Spinning trying to > capture all readers [...] > 2015-12-08 09:15:17,795 INFO > [ValidationExecutor:689]ColumnFamilyStore.java:1923 Spinning trying to > capture released readers [...] > 2015-12-08 09:15:17,795 INFO > [ValidationExecutor:689]ColumnFamilyStore.java:1924 Spinning trying to > capture all readers [...] > (I removed SSTableReader information because it's rather long...
