Sharad Agarwal updated HADOOP-4868:
-----------------------------------
Attachment: 4868_v3.patch
this patch splits the scripts based on the proposal by Owen.
* I have moved the core, mapred and hdfs specific scripts in bin/core,
bin/mapred and bin/hdfs folder. They would get into the respective
$HADOOP_HOME/{core,hdfs,mapred}/bin folder when structure in repository is
changed.
* Added mapred-config.sh and hdfs-config.sh. These invoke the common-config.sh
present in the core. Note I renamed the hadoop-config.sh to common-config.sh
and moved some of the stuff from the old hadoop script to it. The idea is that
common-config.sh will contain things which is common for all the sub projects.
* common-config.sh loads the hdfs libraries if it is present (for fs command to
work for hdfs)
* conf is in $HADOOP_HOME
* hadoop script continue to work for all the commands but its usage for mapred
or hdfs commands has been deprecated.
* I have put couple of TODO markers at places where the value of environment
variable needs to be changed when the change in structure happens.
