LocalFile ignores active container and HDataStorage can't copy to other
DataStrorage
------------------------------------------------------------------------------------
Key: PIG-145
URL: https://issues.apache.org/jira/browse/PIG-145
Project: Pig
Issue Type: Bug
Components: impl
Reporter: Charlie Groves
Attachments: PIG-145-DataStorage_Bugs.patch
As part of starting to rewrite the DataStorage APIs, I wrote some unit tests
for the existing DataStorage implementations to make sure I wasn't breaking
anything. In testing the open code, I found that LocalFile doesn't respect the
active container you set you LocalDataStorage, so if you open a relative file,
it's relative to wherever you're running the code. Similarly, while testing
the copy operations, I found that HFile doesn't allow copying to anything other
than other HFiles and that HDirectory's copy operation was never used because
it had the wrong signature.
The attached patch fixes these issues and adds tests for much of the
DataStorage API for both of the existing backends. There are no tests for the
sopen code as I'm planning on changing that significantly in rewriting these.
