Daniel Dai commented on PIG-4395:
---------------------------------
We don't need Hadoop in local mode since Pig bundles Hadoop in distribution in
theory. However, the bundled Hadoop is not compiled against Windows. AFAIK,
Hadoop 2.6.0 supports Windows, but you will need to recompile under Windows. So
far, I only tested Pig Windows with HDP, which has the Hadoop Windows binary.
