> 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.
>  !screenshot-2.png! 
> The fix is trivial. Just free the slot when InvalidToken exception is thrown.
