------------------------------------------
Test and Documentation Plan: ci
Status: Patch Available (was: In Progress)
> Implement atomic heartbeat file write
> -------------------------------------
>
> Key: CASSANDRA-21290
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21290
> Project: Apache Cassandra
> Issue Type: Bug
> Components: Legacy/Core
> Reporter: John Lu
> Assignee: John Lu
> Priority: Normal
>
> It is possible for an empty heartbeat file to be written, potentially due to
> crash between file creation and the actual write. We can instead write to a
> temporary heartbeat file and then do an atomic move to rename it to the
> actual heartbeat file.
>
> Also fall back to the last modified time of the heartbeat file in case the
> file is not able to be parsed (it wont be able to be parsed if its empty)
