Benjamin Roth commented on CASSANDRA-12844:
-------------------------------------------
Can you reproduce that? Or in other words, are you sure, the bare "nodetool
drain" caused that? Or is it possible that the process has been killed in the
middle? A drain itself should not write or or truncate or do anything else with
hints. A drain is just flushing all memtables and shutting down thrift + native
transport. Hints are created locally if outgoing requests fail, so this is sth
really different.
I'm asking as I did many many drains (3.10) and never had such an issue.

> Key: CASSANDRA-12844
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12844
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Harikrishnan
> Priority: Critical
> Labels: hints
>
> The steps are as follows.
> we have 4/4 node cassandra running in 3.9 version.
> In one node made some changes to cassanra.yaml. issued a nodetool drain
> killed the cassandra process and restarted the node. After sometime nodetool
> status reported multiple nodes are down in that DC.
> Went and check the system.log of all the files and found the hint corruption
> occuring(CASSANDRA-12728). nodetool drain causing this corruption and
> bringing multiple nodes down is a big concern.
