Subject [jira] [Commented] (HADOOP-7438) Using the hadoop-deamon.sh script to start nodes leads to a depricated warning
Date Thu, 07 Jul 2011 17:33:16 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7438?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13061452#comment-13061452
] 

Eric Yang commented on HADOOP-7438:
-----------------------------------

The recent changes is to ensure that hadoop-common, hadoop-hdfs, hadoop-mapreduce are installed
to the same location. i.e. hadoop-[common|hdfs|mapreduce]-0.23.0/* move to /usr directory.
 This may not seem intuitive if user decided to keep hadoop bits in three separated directories.
 How about we added a IF condition?

How about we check for existence of HADOOP_HDFS_HOME variable? if this is defined, use HADOOP_HDFS_HOME/bin/hdfs.
 If it does not exist, then fallback to HADOOP_PREFIX/bin/hdfs.  This will ensure the script
works for separated directories and as merged directory.

> hadoop-daemon.sh calls common/bin/hadoop for hdfs/bin/hdfs tasks and so common/bin/hadoop
complains its deprecated for those uses.
