This prevents us from using pipes with HBase's TableInputFormat, HRegionPartitioner, etc. > Here is a rough proposal for how to accomplish this: > * Add a new package org.apache.hadoop.mapreduce.pipes that uses the new mapred API. > * the new pipes package will run side by side with the old one. old one should get deprecated at some point. > * the wire protocol used between PipesMapper and PipesReducer and C++ programs must not change. > * bin/hadoop should support both pipes (old api) and pipes2 (new api) > Does this sound reasonable? -- This message was sent by Atlassian JIRA (v6.2#6252)
