Allen Wittenauer commented on MAPREDUCE-1362: --------------------------------------------- Kicked off a fresh Jenkins run. Not sure why there isn't one. > Pipes should be ported to the new mapreduce API > ----------------------------------------------- > > Key: MAPREDUCE-1362 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1362 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: pipes > Reporter: Bassam Tabbara > Labels: BB2015-05-TBR > Attachments: MAPREDUCE-1362-trunk.patch, MAPREDUCE-1362.patch, > MAPREDUCE-1362.patch > > > Pipes is still currently using the old mapred API. 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 (v6.3.4#6332)
