Re: HADOOP_HOME depracated
Thanks, for your reply. It would be great to mention this in your tutorial on your web sites. Is the name of the HADOOP_PREFIX/HOME/INSTALL crucial to Hadoop, or it's just user benefit to set this variable. Thanks for reply.

You can set HADOOP_PREFIX, or set HADOOP_HOME_WARN_SUPPRESS in your environment to a non-empty value to suppress the warning.

Re: HADOOP_HOME depracated
Hi, Agree that would be great to do since its an incompatible change (going forward). Would you like to contribute a doc fix for this? I do believe the other (client-oriented) components in the Hadoop ecosystem, such as Pig, Hive, etc. can reuse HADOOP_HOME/etc. if set, for some benefits (such as reading discovering the right cluster, etc.). I'd say its primarily user benefit. P.s. For 1.x, you may also want to instead use packages offered via Apache Bigtop: https://cwiki.apache.org/confluence/display/BIGTOP/How+to+install+Hadoop+distribution+from+Bigtop, which offers an integration-tested stack of ecosystem components (i.e. proper, working version bundles).

HADOOP_HOME depracated
Hello, why when running Hadoop, there is always HADOOP_HOME shell variable being told to be deprecated. How to set installation directory on cluster nodes, which variable is correct. Thanks Ondrej Klimpera
