Eugene Koifman commented on HIVE-4896:
--------------------------------------

with core and hcatalog-pig-adapter under org.apache.hcatalog brought from 0.11 
1 test fails:

TestSemanticAnalysis#testAddReplaceCols()
        Failure expected:<0> but was:<1> 

junit.framework.AssertionFailedError: expected:<0> but was:<1>
at 
org.apache.hcatalog.cli.TestSemanticAnalysis.testAddReplaceCols(TestSemanticAnalysis.java:212)

The reason is that for RCFILE the default in 0.12 is LazyBinaryColumnarSerDe 
(hive.default.rcfile.serde) which doesn't allow updating columns.  
                
> create binary backwards compatibility layer hcatalog 0.12 and 0.11

>          Issue Type: Sub-task
>          Components: HCatalog
>    Affects Versions: 0.12.0
>            Reporter: Eugene Koifman
>            Assignee: Eugene Koifman
>             Fix For: 0.12.0

>   Original Estimate: 72h
>  Remaining Estimate: 72h
>
> 1. create a 011 dir in each HCat submodule to hold these classes
> 2. update build to place these classes into jars
> 3. figure out how to test this
> The goal is for users who were using public API (e.g. HCatLoader) in their 
> programs to be able to upgrade to hive 0.12 and have their programs still 
> work without change.
> The compatibility layer will have a sunset clause to be removed in 2 releases.
