Rohini Palaniswamy commented on PIG-3285:
-----------------------------------------
Not too many code paths. For hbase storage, need to write a method that
* Filters out pig and hadoop classes from the list of classes so that pig
and hadoop jar are not included.
* Find the jars for the other classes and filter out any jars already
present in PigContext.extrajars and add only the rest to tmpjars.
Also ensure that you add HTable.class apart from Zookeeper, inputformat,
input/output key/value, partitioner and combiner classes.
> Jobs using HBaseStorage fail to ship dependency jars
