---------------------------------------
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.
