> Short circuit read leaks Slot objects when InvalidToken exception is thrown
> ---------------------------------------------------------------------------

> Key: HDFS-16198
> URL: https://issues.apache.org/jira/browse/HDFS-16198
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Eungsop Yoo
> Priority: Major

>
> In secure mode, 'dfs.block.access.token.enable' should be set 'true'. With
> this configuration SecretManager.InvalidToken exception may be thrown if the
> access token expires when we do short circuit reads. It doesn't matter
> because the failed reads will be retried. But it causes the leakage of
> ShortCircuitShm.Slot objects. We found this problem in our secure HBase
> clusters.
> The fix is trivial. Just free the slot when InvalidToken exception is thrown.
