Hi Preston,
thanks for doing this!
I think that I can take a look at points 1 and 2, but probably not
before the weekend.
For point 3 I think that mini dfs is part of regular hadoop, so this
might just be a maven dependency (unless we have our own wrapper).
Probably Ian could answer the question with a single look at the code in
question.
Cheers,
Till

I started working on a branch for going to Hyracks 0.3.0 [1]. The
process was a lot more involved than I expected. We have two larger
changes: error handling and UTF8StringPointable storage format change.
I have a few questions and could use some help in getting this upgrade
ready.
ERROR HANDLING
HyracksDataException now extends IOException. In VXQuery
SystemException extends HyracksDataException. This means we have some
various changes with respect to which exception to throw or catch. I
could use a second pair of eyes to verify my update is handling
exceptions correctly. **Help Point 1**
In addition the exception changes now cause the test suite to fail on
tests that are supposed to find a SystemException error code. **Help
Point 2**
HDFS TESTING
To test HDFS we use a class class called MiniDFS. For some reason, the
class is no longer included in our packages. We need to find it and
include it. **Help Point 3**
INDEXING UPDATE
Due to the changes to UTF8StringPointable many of the places where we
had previously hard coded a string length to be 2 bytes needs to be
changed. Indexing does not currently work because of these issues.
**Help Point 4**
JSON UPDATE
Due to the changes to UTF8StringPointable many of the places where we
had previously hard coded a string length to be 2 bytes needs to be
changed. JSONiq has a few issues because of these changes. **Help
Point 5**
I would appreciate some support (or at least some feedback) on fixing
the first three points. The last two points needs someone who will
actually test and write some code.
Thanks
Preston

The current release version for AsterixDB is 0.9.0. I think that for
some reason that tag didn’t make it to the GitHub mirror. Also the
Hyracks 0.3.1 release is in progress. Unfortunately, I haven’t
recently looked what it would take to update, but I think that it
would be really good to do it …

Has anyone looked at what it would take to update VXQuery to the
latest version of Hyracks? It seems the project has had a few
releases
since joining Apache.
VXQuery Hyracks version: 0.2.17-incubating
Current Hyracks version: 0.3.X
Also, do you know what is the current release version? The project
website says 0.9 for AsterixDB, but I am not sure about the Hyracks
sub-project. The github mirror only shows branches with release
versions up to 0.8.9.
