Eugene Koifman commented on HIVE-5274:
--------------------------------------
I think no end user app should be mixing org.apache.hcatalog.* and
org.apache.hive.hcatalog.* - in fact we should probably make that clear in the
doc/rel notes.
so the user has 2 options:
1. use deprecated org.apache.hcatalog (including hcat storage handler)
2. switch to new org.apache.hive.hcatalog and get new HBaseStorageHandler
so I think your option 'b' is the right one
> HCatalog package renaming backward compatibility follow-up

> Key: HIVE-5274
> URL: https://issues.apache.org/jira/browse/HIVE-5274
> Project: Hive
> Issue Type: Bug
> Components: HCatalog
> Affects Versions: 0.12.0
> Reporter: Sushanth Sowmyan
> Assignee: Sushanth Sowmyan
> Fix For: 0.12.0
>
>
> As part of HIVE-4869, the hbase storage handler in hcat was moved to
> org.apache.hive.hcatalog, and then put back to org.apache.hcatalog since it
> was intended to be deprecated as well.
> However, it imports and uses several org.apache.hive.hcatalog classes. This
> needs to be changed to use org.apache.hcatalog classes.
> ==
> Note : The above is a complete description of this issue in and of by itself,
> the following is more details on the backward-compatibility goal I have(not
> saying that each of these things are violated) :
> a) People using org.apache.hcatalog packages should continue being able to
> use that package, and see no difference at compile time or runtime. All code
> here is considered deprecated, and will be gone by the time hive 0.14 rolls
> around. Additionally, org.apache.hcatalog should behave as if it were 0.11
> for all compatibility purposes.
> b) People using org.apache.hive.hcatalog packages should never have an
> org.apache.hcatalog dependency injected in.
> Thus,
> It is okay for org.apache.hcatalog to use org.apache.hive.hcatalog packages
> internally (say HCatUtil, for example), as long as any interfaces only expose
> org.apache.hcatalog.\* For tests that test org.apache.hcatalog.\*, we must be
> capable of testing it from a pure org.apache.hcatalog.\* world.
> It is never okay for org.apache.hive.hcatalog to use org.apache.hcatalog,
> even in tests.
