---------------------------------------
Summary: CryptoInputStream throwing wrong exception class on erros
Key: HADOOP-11042
URL: https://issues.apache.org/jira/browse/HADOOP-11042
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 3.0.0
Reporter: Steve Loughran
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.
