--------------------------------------
Summary: Failed compaction is not captured
Key: CASSANDRA-13833
URL: https://issues.apache.org/jira/browse/CASSANDRA-13833
Project: Cassandra
Issue Type: Bug
Components: Compaction
Reporter: Jay Zhuang
Assignee: Jay Zhuang
Follow up for CASSANDRA-13785, when the compaction failed, it fails silently.
No error message is logged and exceptions metrics is not updated. Basically,
it's unable to get the exception:
[CompactionManager.java:1491|https://github.com/apache/cassandra/blob/cassandra-2.2/src/java/org/apache/cassandra/db/compaction/CompactionManager.java#L1491]
Here is the call stack:

There're 2 {{FutureTask}} in the call stack, for example
{{FutureTask1(FutureTask2))}}, If the call thrown an exception, {{FutureTask2}}
sets the status, save the exception and return. But FutureTask1 doesn't get any
exception, then set the status to normal. So we're unable to get the exception
