can any boby help to set the Environment Variables ?please!!!!!

[yi-chia wang]

Rhipe requires HADOOP_HOME or HADOOP or HADOOP_BIN environment variable to be present
 $HADOOP/bin/hadoop or $HADOOP_BIN/hadoop should exist
Rhipe: HADOOP_BIN is missing, using $HADOOP/bin
HADOOP_HOME missing
HADOOP_CONF_DIR missing, you are probably going to have a problem running RHIPE.
HADOOP_CONF_DIR should be the location of the directory that contains the configuration files
------------------------------------------------
| Please call rhinit() else RHIPE will not run |
------------------------------------------------

* DONE (Rhipe)

Prerequisite 4: Environment Variables
In order for RHIPE to compile and work correctly, it is good to ensure that the following environment variables are set appropriately:
PKG_CONFIG_PATH: make sure this contains a path to where the protobuf*.pc files are located.
LD_LIBRARY_PATH: points to the path where R.so and Rhipe.so are located (typically something like __PREFIX__/lib64/R/lib).
HADOOP: points to the Hadoop installation directory. It is expected that $HADOOP/bin contains the Hadoop shell executable hadoop.
