Duo Zhang commented on HBASE-14949:
-----------------------------------
Seems all failed tests are cause by error executing shell command, something
like
{noformat}
java.io.IOException: java.util.concurrent.ExecutionException:
java.lang.RuntimeException: Error while running command to get file permissions
: ExitCodeException exitCode=127: /bin/ls: error while loading shared
libraries: libc.so.6: failed to map segment from shared object: Permission
denied
{noformat}
I assume docker should not have these problems? [~busbey] Thanks.

> The AsyncFSHLog introduced in HBASE-14790 may write same WAL entries to
> different WAL files. WAL entry itself is idempotent so replay is not a
> problem but the intermediate file name and final name when splitting is
> constructed using the lowest or highest sequence id of the WAL entries
> written, so it is possible that different WAL files will have same
> intermediate or final file name when splitting. In the currentm
> implementation, this will cause split fail or data loss. We need to solve
> this.
