5. Set Up the HDFS User and Prepare WebHCat Directories On HDFS

Set up the HDFS user. Login as $HDFS_USER

 hadoop fs -mkdir /user/$WEBHCAT_USER 
hadoop fs -chown -R $WEBHCAT_USER:$WEBHCAT_USER /user/$WEBHCAT_USER 
hadoop fs -mkdir /apps/webhcat 

Prepare WebHCat directories on HDFS.

hadoop dfs -copyFromLocal /usr/share/HDP-webhcat/pig.tar.gz /apps/webhcat/
hadoop dfs -copyFromLocal /usr/share/HDP-webhcat/hive.tar.gz /apps/webhcat/
hadoop dfs -copyFromLocal /usr/lib/hadoop/contrib/streaming/hadoop-streaming*.jar /apps/webhcat/

Set appropriate permissions for the HDFS user and the webhcat directory.

hadoop fs -chown -R $WEBHCAT_USER:users /apps/webhcat 
hadoop fs -chmod -R 755 /apps/webhcat
