Removed mention of all of the HADOOP_* environment variables. Made HBASE_* equivs. hbase-env.sh is not near dup of hadoop-env.sh. Removed options on scripts that used take both hbase and hadoop conf and home. Now we just work w/ hbase. Fixed logging (logs dir now under hbase). git-svn-id: https://svn.apache.org/repos/asf/hadoop/hbase/trunk@618765 13f79535-47bb-0310-9956-ffa450edef68
