+# Secure Docker-compose with KMS, Yarn RM and NM
+This docker compose allows to test Sample Map Reduce Jobs with OzoneFileSystem
+It is a superset of ozonesecure docker-compose, which add Yarn NM/RM in addition
+to Ozone OM/SCM/NM/DN and Kerberos KDC.
+
+## Basic setup
+
+```
+cd hadoop-ozone/dist/target/ozone-0.5.0-SNAPSHOT/compose/ozonesecure-mr
+
+docker-compose up -d
+```
+
+## Ozone Manager Setup
+
+```
+docker-compose exec om bash
+
+kinit -kt /etc/security/keytabs/testuser.keytab testuser/om@EXAMPLE.COM
+
+ozone sh volume create /vol1
+
+ozone sh bucket create /vol1/bucket1
+
+ozone sh key put /vol1/bucket1/key1 LICENSE.txt
+
+ozone fs -ls o3fs://bucket1.vol1/
+```
+
+## Yarn Resource Manager Setup
+```
+docker-compose exec rm bash
+
+kinit -kt /etc/security/keytabs/hadoop.keytab hadoop/rm@EXAMPLE.COM
+export HADOOP_MAPRED_HOME=/opt/hadoop/share/hadoop/mapreduce
+
+export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/opt/hadoop/share/hadoop/mapreduce/*:/opt/ozone/share/ozone/lib/hadoop-ozone-filesystem-lib-current-0.5.0-SNAPSHOT.jar
+
+hadoop fs -mkdir /user
+hadoop fs -mkdir /user/hadoop
+```
+
+## Run Examples
+
+### WordCount
+Status: Fully working with HDDS-1299
+```
+yarn jar $HADOOP_MAPRED_HOME/hadoop-mapreduce-examples-*.jar wordcount o3fs://bucket1.vol1/key1 o3fs://bucket1.vol1/key1.count
+
+hadoop fs -cat /key1.count/part-r-00000
+```
+
+### Pi
+Status: Not fully working yet, tracked by HDDS-1317
+```
+yarn jar $HADOOP_MAPRED_HOME/hadoop-mapreduce-examples-*.jar pi 10 100
+```
+
+### RandomWrite
+Status: Not fully working yet, tracked by HDDS-1317
+```
+yarn jar $HADOOP_MAPRED_HOME/hadoop-mapreduce-examples-*.jar randomwriter -Dtest.randomwrite.total_bytes=10000000  o3fs://bucket1.vol1/randomwrite.out
+```
