Eric Yang commented on HADOOP-7563:
-----------------------------------
The missing class in from hadoop-alfredo module. Alejandro has made
hadoop-common depends on hadoop-alfredo, but there is no script to package
hadoop-alfredo-0.23.0-SNAPSHOT.jar file into
hadoop-common-0.23.0-SNAPSHOT/share/hadoop/common. If you manually copy it
over there, then it is possible to use the scripts to start HDFS in both merged
layout as well as separated layout using HADOOP_COMMON_HOME and
HADOOP_HDFS_HOME environment variables. Fixing alfredo is in HADOOP-7560. I
think this jira and HDFS-2277 are ready to be committed to contain the scope of
the changes and keep things clean.
> hadoop-config.sh setup HADOOP_HDFS_HOME and HADOOP_MAPRED_HOME incorrectly

> HADOOP_HDFS_HOME and HADOOP_MAPRED_HOME was set to
> HADOOP_PREFIX/share/hadoop/hdfs and HADOOP_PREFIX/share/hadoop/mapreduce.
> This setup confuses the location of hdfs and mapred scripts. Instead the
> script should look for hdfs and mapred script in HADOOP_PREFIX/bin.
