Shao-Chuan Wang updated CASSANDRA-6469:
---------------------------------------
Fix Version/s: (was: 2.0.1)
> FSError in
> org.apache.cassandra.io.compress.CompressedRandomAccessReader.reBuffer
> ---------------------------------------------------------------------------------
>
> Key: CASSANDRA-6469
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6469
> Project: Cassandra
> Issue Type: Bug
> Environment: Linux
> Reporter: Shao-Chuan Wang
>
> We are seeing FSError in the code path of SSTableReader. Noted that, the file
> can be read, so suggesting it should not be the file corruption.
> The FileChannel is closed when it tries to call position(). It is not very
> easily reproducible. We'll paste here if we hit this again. Thank you.
