$HADOOP_PREFIX/bin/yarn should set defaults for $HADOOP_*_HOME
--------------------------------------------------------------
Key: MAPREDUCE-3456
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3456
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.0
Reporter: Eric Payne
If the $HADOOP_PREFIX/hadoop-dist/target/hadoop-0.23.0-SNAPSHOT.tar.gz tarball
is used to distribute hadoop, all of the HADOOP components (HDFS, MAPRED,
COMMON) are all under one directory. In this use case, HADOOP_PREFIX should be
set and should point to the root directory for all components, and it should
not be necessary to set HADOOP_HDFS_HOME, HADOOP_COMMON_HOME, and
HADOOP_MAPRED_HOME. However, the $HADOOP_PREFIX/bin/yarn script requires these
3 to be set explicitly in the calling environment or it won't run.
$HADOOP_PREFIX/bin/yarn should check if $HADOOP_PREFIX is set and, if it is,
use that value for the 3 other HADOOP_*_HOME variables.
