Subject [jira] [Commented] (HBASE-9165) Improvements to addDependencyJars
Date Fri, 30 Aug 2013 20:58:52 GMT

Daniel Dai commented on HBASE-9165:
-----------------------------------

+1. Pig need this feature to ship HBase dependent jars correctly. Currently Pig user have
to register HBase dependent jars (such as protobuf.jar) to use HBaseStorage.

> The way we support adding HBase dependencies to a MapReduce job in {{TableMapReduceUtils#addDependencyJars(job)}}
is a bit monolithic. Advanced users need a way to add HBase and its dependencies to their
job without us snooping around for ouput formats and the like (see PIG-3285). We can also
benefit from a little more code reuse between our {{mapred}} and {{mapreduce}} namespaces.
