How to Send Email Using Oozie (For Beginners)

The steps to send an Email through Oozie, for the first time.

Please note that I'm using Cloudera cdh5.13!

First start with smtp configuration in oozie-site.xml:

Oozie > Configuration > Oozie Server

Click here to view oozie-site.xml configuration in Cloudera Manager

<property>
  <name>oozie.email.smtp.host</name>
  <value>localhost</value>
</property>
<property>
  <name>oozie.email.from.address</name>
  <value>oozie@localhost/value>
</property>
<property>
  <name>oozie.email.smtp.auth</name>
  <value>false</value>
</property>
<property>
  <name>oozie.email.smtp.username</name>
  <value></value>
</property>
<property>
  <name>oozie.email.smtp.password</name>
  <value></value>
</property>
<property>
  <name>oozie.email.smtp.port</name>
