Zhe Zhang commented on HDFS-8272:
---------------------------------
Sounds good. I guess we can mock returning a bad token / encryption key at
first request and a good one on second req. Also we can mock a transient DN
failure.

> Currently in DFSStripedInputStream the retry logic is still the same with
> DFSInputStream. More specifically, every failed read will try to search for
> another source node. And an exception is thrown when no new source node can
> be identified. This logic is not appropriate for EC inputstream and can be
> simplified.
