Thanks Steve for taking a look, will rebase/update the patch.
> CryptoInputStream throwing wrong exception class on errors
> ----------------------------------------------------------
>
> Key: HADOOP-11042
> URL: https://issues.apache.org/jira/browse/HADOOP-11042
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs

> Having had a quick look at the {{CryptoInputStream}} class, it's not in sync
> with all the other filesystem's exception logic, as specified in
> {{src/site/markdown/filesystem/fsdatainputstream.md}}
> Operations MUST throw an {{IOException}} on out of bounds reads, ideally
> {{EOFException}} :
> # {{read(byte[] b, int off, int len)}}
> # {{seek(long pos) }}
> # {{seekToNewSource}}
> The tests you want to extend to verify expected behaviour are in
> {{AbstractContractOpenTest}} and {{AbstractContractSeekTest}}
> also, the {{HasEnhancedByteBufferAccess}} implementations may want to think
> about using {{checkStream()}} before acting on a potentially closed stream.
