         <p>Apache Eagle (called Eagle in the following) can be developed in popular IDE, e.g. Intellij and Eclipse. Here we focus on development in Intellij.</p>

 <h3 id="1-prepare-hadoop-environment">1. Prepare Hadoop<sup id="fnref:HADOOP"><a href="#fn:HADOOP" class="footnote">1</a></sup> environment</h3>

 <p>Normally HDP sandbox is needed for testing Hadoop monitoring. Please reference <a href="/docs/quick-start.html">Quick Start</a> for setting up HDP sandbox.</p>

 <p>Please ensure following daemons are up</p>

 <ul>
   <li>
     <p>Namenode</p>
   </li>
   <li>
     <p>Datanode</p>
   </li>
   <li>
     <p>HBase<sup id="fnref:HBASE"><a href="#fn:HBASE" class="footnote">2</a></sup> master/region server only needed when HBase is metadata store</p>
   </li>
   <li>
     <p>MySQL only neede when MySQL is metadata store</p>
   </li>
   <li>
     <p>Zookeeper<sup id="fnref:ZOOKEEPER"><a href="#fn:ZOOKEEPER" class="footnote">3</a></sup></p>
   </li>
   <li>
     <p>Kafka<sup id="fnref:KAFKA"><a href="#fn:KAFKA" class="footnote">4</a></sup></p>
   </li>
 </ul>

 <h3 id="2-start-eagle-web-service-in-intellij">2. Start Eagle web service in Intellij</h3>

 <p>Import source code into Intellij, and find eagle-webservice project. Intellij Ultimate supports launching J2EE server within Intellij. If you don’t have
 Intellij Ultimate version, Eclipse is another option.</p>

 <ul>
   <li><strong>Check service configuration</strong></li>
 </ul>

 <p>Under eagle-webservice/src/main/resources, configure application.conf for metadata store. As of Eagle 0.4.0, by default, it points to sandbox HBase. If you want to use MySQL as metadata store, just copy application-mysql.conf to application.conf.</p>

 <ul>
   <li><strong>Ensure tables are created</strong></li>
 </ul>

 <p>Run eagle-service-init.sh under eagle-assembly/src/main/bin/eagle-service-init.sh to create metadata tables.</p>

 <ul>
   <li><strong>Start Eagle service</strong></li>
 </ul>

 <p>Configure Intellij for running Apache Tomcat server with eagle-service artifacts</p>

 <h3 id="3-start-topology-in-intellij">3. Start topology in Intellij</h3>

 <ul>
   <li><strong>Check topology configuration</strong></li>
 </ul>

 <p>Take HDFS data activity monitoring as example, config application.conf under eagle-security/eagle-security-hdfs-securitylog/src/main/resources for eagle service endpoint, Kafka endpoint etc.</p>

 <ul>
   <li><strong>Start Storm<sup id="fnref:STORM"><a href="#fn:STORM" class="footnote">5</a></sup> topology</strong></li>
 </ul>

 <p>Normally one data source has one correponding Storm topology, for example to monitor HDFS data activity, org.apache.eagle.security.auditlog.HdfsAuditLogProcessorMain is used for starting Storm topology and reading audit logs from Kafka.</p>

 <p>Other example data integrations are as follows</p>

 <p>Hive query activity monitoring : org.apache.eagle.security.hive.jobrunning.HiveJobRunningMonitoringMain</p>

 <p>HBase data activity monitoring: org.apache.eagle.security.hbaseHbaseAuditLogMonitoringTopology</p>

 <p>MapR FS data activity monitoring: org.apache.eagle.security.auditlog.MapRFSAuditLogProcessorMain</p>

	<li><strong>Check service configuration</strong></li>
	</ul>

	<p>Under eagle-webservice/src/main/resources, configure application.conf for metadata store. As of Eagle 0.4.0, by default, it points to sandbox HBase. If you want to use MySQL as metadata store, just copy application-mysql.conf to application.conf.</p>

	<ul>
	<li><strong>Ensure tables are created</strong></li>
	</ul>

	<p>Run eagle-service-init.sh under eagle-assembly/src/main/bin/eagle-service-init.sh to create metadata tables.</p>

	<ul>
	<li><strong>Start Eagle service</strong></li>
	</ul>

	<p>Configure Intellij for running Apache Tomcat server with eagle-service artifacts</p>

	<h3 id="3-start-topology-in-intellij">3. Start topology in Intellij</h3>

	<ul>
	<li><strong>Check topology configuration</strong></li>
	</ul>

	<p>Take HDFS data activity monitoring as example, config application.conf under eagle-security/eagle-security-hdfs-securitylog/src/main/resources for eagle service endpoint, Kafka endpoint etc.</p>

	<ul>
	<li><strong>Start Storm<sup id="fnref:STORM"><a href="#fn:STORM" class="footnote">5</a></sup> topology</strong></li>
	</ul>

	<p>Normally one data source has one correponding Storm topology, for example to monitor HDFS data activity, org.apache.eagle.security.auditlog.HdfsAuditLogProcessorMain is used for starting Storm topology and reading audit logs from Kafka.</p>

	<p>Other example data integrations are as follows</p>

	<p>Hive query activity monitoring : org.apache.eagle.security.hive.jobrunning.HiveJobRunningMonitoringMain</p>

	<p>HBase data activity monitoring: org.apache.eagle.security.hbaseHbaseAuditLogMonitoringTopology</p>

	<p>MapR FS data activity monitoring: org.apache.eagle.security.auditlog.MapRFSAuditLogProcessorMain</p>
