I suggest as a workaround making the forceUserDefinedCompaction method
ignore disk space estimates and attempt the requested compaction even
if it guesses it will not have enough space. This would allow you to
submit the 2 sstables you want manually.

Running at 78% disk capacity is somewhat out there on the edge.
The CompactionManager is showing that compactions are backing up. I'm guessing
this has to do with the minor compactions not been able compact the list of
files they want to, so it cannot reduce the number of files each compaction
Thank you, Naren.
I'll add some more details and upload it to FAQ wiki page.

It will work as long as thrift and gossip are bound to the same
interface. The discovery server in Hector also uses the
CassandraHostConfigurator#getPort for the port in constructing the

Hi,
My service is not yet ready to be fully multi-DC, due to how some of my
legacy MySQL stuff works. But, I wanted to get cassandra going ASAP and
work towards multi-DC. I have two main cassandra use cases: one where I can
handle eventual consistency (and all of the writes/reads are currently O
The latter.

Hi Aaron,
Maybe, my previous description was not good. It's not a compaction
threshold problem.
In fact, Cassandra tries to compact 7 sstables in the minor
compaction. But it decreases the number of sstables one by one due to
insufficient disk space. At the end, it compacts a single file as in

This is incorrect. Depending on the nature of the corruption it may
spread to other nodes. Checksumming (done right) would be a great
addition to alleiate this. Yes, there is code that tri
Want to check if you are talking about minor compactions or major (nodetool)
compactions.
What settings compaction settings do you have for this CF ? You can increase
the min compaction threshold and reduce the frequency of compactions
