------------------------------------------
Summary: Add details to Error message: Not enough space for
compaction
Key: CASSANDRA-18260
URL: https://issues.apache.org/jira/browse/CASSANDRA-18260
Project: Cassandra
Issue Type: Improvement
Components: Observability/Logging
Reporter: Brad Schoening
When compaction fails, the log message should list a) the free space available
on disk at that point in time and b) perhaps the number and/or size of the
source sstables being compacted.
Free space can change from one moment to the next, so when the below compaction
failed because it needed 161GB, upon checking the server a few minutes later,
it had 184GB free. Similarly, the error message mentions it was writing out
one SSTable on this STCS table, but its not clear if it was combining X -> 1
tables, or something else.
