---------------------------------------------------------------------
[~aboudreault] could you test this patch? I have not been able to reproduce
this myself
Patch just makes sure all compactions are finished before waiting for the
deletion tasks
Same issue could be in offline cleanup and offline scrub
oh btw, you can make the offline tools log more by changing WARN to DEBUG in
conf/logback-tools.xml if it still fails

> I'm experiencing an issue related to sstablesplit. I would like to understand
> if I am doing something wrong or there is an issue in the split process. The
> process fails randomly with the following exception:
> {code}
> ERROR 02:17:36 Error in ThreadPoolExecutor
> java.lang.AssertionError: Data component is missing for
> sstable./tools/bin/../../data/data/system/compactions_in_progress-55080ab05d9c388690a4acb25fe1f77b/system-compactions_in_progress-ka-16
> {code}
> See attached output.log file. The process never stops after this exception
> and I've also seen the dataset growing indefinitely (number of sstables).
> * I have not been able to reproduce the issue with a single sstablesplit
> command. ie, specifying all files with glob matching.
> * I can reproduce the bug if I call multiple sstablesplit one file at the
> time (the way ccm does)
> Here is the test case file to reproduce the bug:
> https://drive.google.com/file/d/0BwZ_GPM33j6KdVh0NTdkOWV2R1E/view?usp=sharing
> 1. Download the split_issue.tar.gz file. It includes latest cassandra-2.1
> branch binaries.
> 2. Extract it
> 3. CD inside the use case directory
> 4. Download the dataset (2G) just to be sure we have the same thing, and
> place it in the working directory.
> https://docs.google.com/uc?id=0BwZ_GPM33j6KV3ViNnpPcVFndUU&export=download
> 5. The first time, run ./test.sh. This will setup and run a test.
> 6. The next times, you can only run ./test --no-setup . This will only reset
> the dataset as its initial state and re-run the test. You might have to run
> the tests some times before experiencing it... but I'm always able with only
> 2-3 runs.
