Integrate with hadoop

Hadoop is an optional component of zeppelin unless you need the following features

• Use hdfs to store notes.
• Use hdfs to store interpreter configuration
• Use hdfs to store recovery data
• Launch interpreter in yarn mode

Requirements

Zeppelin 0.9 doesn't ship with hadoop dependencies, you need to include hadoop jars by yourself via the following steps

• Hadoop client (both 2.x and 3.x are supported) is installed.
• $HADOOP_HOME/bin is put in PATH. Because internally zeppelin will run command hadoop classpath to get all the hadoop jars and put them in the classpath of Zeppelin.
• Set USE_HADOOP as true in zeppelin-env.sh.
