[jira] [Updated] (CASSANDRA-12655) Incremental repair & compaction
hang on random nodes
[ https://issues.apache.org/jira/browse/CASSANDRA-12655?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Navjyot Nishant updated CASSANDRA-12655:
----------------------------------------
Description:
Hi We are setting up incremental repair on our 18 node cluster. Avg load on each node is ~5GB. The repair run fine on couple of nodes and sudently get stuck on random nodes. Upon checking the system.log of impacted node we dont see much information.
Following are the lines we see in system.log and its there from the point repair is not making progress -
{code}

{code}
When we try to see pending compaction by executing {code}nodetool compactionstats{code} it hangs as well and doesn't return anything. However {code}nodetool tpstats{code} show active and pending compaction which never come down and keep increasing.

The only solution we have is bounce the node and all the pending compactions started getting processed immediately and get processed in 5 - 10 minutes.
This is a road blocker issue for us and and help in this matter would be highly appreciated.
