Subject [jira] [Created] (PIG-3498) Make pig binary work on both HBase version 0.94 and 0.95

---------------------------------------

             Summary: Make pig binary work on both HBase version 0.94 and 0.95
                 Key: PIG-3498
                 URL: https://issues.apache.org/jira/browse/PIG-3498
             Project: Pig
          Issue Type: Task
    Affects Versions: 0.11
            Reporter: Jarek Jarcec Cecho


HBase 0.95+ support has been added via PIG-3390. Whereas pig can be compiled against both
0.94 and 0.95, due to binary incompatibilities inside HBase, pig compiled against HBase 0.95
can't be used against 0.94 and vice versa. 

One of the issue we are facing is HBase class {{RowFilter}}, that changed constructor between
the two HBase releases:

* HBase 0.94  {{RowFilter(CompareOp, WritableByteArrayComparable)}}
* HBase 0.95 {{RowFilter(CompareO, ByteArrayComparable)}}

We are using children of the classes used in second parameter and therefore the same code
compiles against both HBase versions. However as the entire constructor signature is saved
into compiled Java class, generated binaries are compatible with only one HBase version. 

As we're releasing only one pig binary, it would be useful to make Pig compatible with both
versions at the same time.
