------------------------------------------
Summary: sstablesplit fails *randomly* with Data component is
missing
Key: CASSANDRA-8623
URL: https://issues.apache.org/jira/browse/CASSANDRA-8623
Project: Cassandra
Issue Type: Bug
Reporter: Alan Boudreault
Assignee: Marcus Eriksson
Attachments: output.log
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 to reproduce the issue with a single sstablesplit command.
ie, specifying all files with glob matching.
* I can reproduce the if I call multiple sstablesplit on a single file (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.
