--------------------------------------
Summary: 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.
==
In general, our goal for backward compatibility should be the following:
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.
