> This task is to address the following [~daryn]'s comments. Please refer
> HDFS-10285 to see more detailed discussion.

> NamenodeProtocolTranslatorPB
> Most of the api changes appear unnecessary.
> IntraSPSNameNodeContext#getFileInfo swallows all IOEs, based on assumption
> that any and all IOEs means FNF which probably isn’t the intention during rpc
> exceptions.

> {quote}
> StoragePolicySatisfier
> It appears to make back-to-back calls to hasLowRedundancyBlocks and
> getFileInfo for every file. Haven’t fully groked the code, but if low
> redundancy is not the common case, then it shouldn’t be called unless/until
> needed. It looks like files that are under replicated are re-queued again?
