Here is the summary of the steps for setting up Apache Eagle (called Eagle in the following) in Hortonworks sandbox:

• Step 1: Setup sandbox image in a virtual machine
• Step 2: Setup Hadoop¹ environment in sandbox
• Step 3: Download and extract a Eagle release to sandbox
• Step 4: Install Eagle
• Step 5: Stream HDFS audit log

Step 1: Setup sandbox image in a virtual machine

To install Eagle on a sandbox you need to run a HDP sandbox image in a virtual machine with 8GB memory recommended.

1. Get Virtual Box or VMware Virtualization environment
2. Get Hortonworks Sandbox v 2.2.4

Step 2: Setup Hadoop environment in sandbox

1. Launch Ambari² to manage the Hadoop environment
   • Enable Ambari in sandbox http://127.0.0.1:8000 (Click on Enable Button)
   • Login to Ambari UI http://127.0.0.1:8080/ with username and password as "admin"
2. Grant root as HBase³ superuser via Ambari
3. Start Storm⁴, HBase & Kafka⁵, Ambari. Showing Storm as an example below.

Step 3: Download and extract a Eagle release to sandbox

• Download

  • Option 1: Download eagle jar from here.

  • Option 2: Build form source code eagle github. After successful build, ‘eagle-xxx-bin.tar.gz’ will be generated under ./eagle-assembly/target

    # installed npm is required before compiling
    $ mvn clean install -DskipTests=true
    

• Copy and extract the package to sandbox

  #extract
  $ tar -zxvf eagle-0.1.0-bin.tar.gz
  $ mv eagle-0.1.0 /usr/hdp/current/eagle
  

Step 4: Install Eagle in Sandbox

The following installation actually contains installing and setting up a sandbox site with three data sources HdfsAuditLog, HiveQueryLog, and User Profiles

• Option 1: Install Eagle using command line

  $ cd /usr/hdp/current/eagle
  $ examples/eagle-sandbox-starter.sh
  

• Option 2: Install Eagle using Eagle Ambari plugin

Step 5: Stream HDFS audit log

To stream HDFS audit log into Kafka, the last step is to install a namenode log4j Kafka appender (another option Logstash is here).

• Step 1: Configure Advanced hadoop-log4j via Ambari UI, and add below "KAFKA_HDFS_AUDIT" log4j appender to hdfs audit logging.

  log4j.appender.KAFKA_HDFS_AUDIT=org.apache.eagle.log4j.kafka.KafkaLog4jAppender
  log4j.appender.KAFKA_HDFS_AUDIT.Topic=sandbox_hdfs_audit_log
  log4j.appender.KAFKA_HDFS_AUDIT.BrokerList=sandbox.hortonworks.com:6667
  log4j.appender.KAFKA_HDFS_AUDIT.KeyClass=org.apache.eagle.log4j.kafka.hadoop.AuditLogKeyer
  log4j.appender.KAFKA_HDFS_AUDIT.Layout=org.apache.log4j.PatternLayout
  log4j.appender.KAFKA_HDFS_AUDIT.Layout.ConversionPattern=%d{ISO8601} %p %c{2}: %m%n
  log4j.appender.KAFKA_HDFS_AUDIT.ProducerType=async
  #log4j.appender.KAFKA_HDFS_AUDIT.BatchSize=1
  #log4j.appender.KAFKA_HDFS_AUDIT.QueueSize=1
  

  

• Step 3: Edit Advanced hadoop-env via Ambari UI, and add the reference to KAFKA_HDFS_AUDIT to HADOOP_NAMENODE_OPTS.

  -Dhdfs.audit.logger=INFO,DRFAAUDIT,KAFKA_HDFS_AUDIT
  

  

• Step 4: Edit Advanced hadoop-env via Ambari UI, and append the following command to it.

  export HADOOP_CLASSPATH=${HADOOP_CLASSPATH}:/usr/hdp/current/eagle/lib/log4jkafka/lib/*
  

  

• Step 5: save the changes and restart the namenode.

• Step 6: Check whether logs are flowing into topic sandbox_hdfs_audit_log

  $ /usr/hdp/current/kafka-broker/bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic sandbox_hdfs_audit_log
  

Now please login to Eagle web http://localhost:9099/eagle-service with account admin/secret, and try the sample demos on Quick Starer

(If the NAT network is used in a virtual machine, it's required to add port 9099 to forwarding ports)
