2. Set Directories and Permissions

Create directories and configure ownership and permissions on the appropriate hosts as described below.

If any of these directories already exist, delete and recreate them. Use the following instructions to set up Oozie configuration files:

We strongly suggest that you edit and source the bash script files included in the companion files (downloaded in Download Companion Files).
Alternatively, you can also copy the contents to your ~/.bash_profile) to set up these environment variables in your environment.
Execute the following commands on your Oozie server:
```
mkdir -p $OOZIE_DATA;
chown -R $OOZIE_USER:$HADOOP_GROUP $OOZIE_DATA;
chmod -R 755 $OOZIE_DATA;
```
```
mkdir -p $OOZIE_LOG_DIR;
chown -R $OOZIE_USER:$HADOOP_GROUP $OOZIE_LOG_DIR;
chmod -R 755 $OOZIE_LOG_DIR;
```
```
mkdir -p $OOZIE_PID_DIR;
chown -R $OOZIE_USER:$HADOOP_GROUP $OOZIE_PID_DIR;
chmod -R 755 $OOZIE_PID_DIR;
```
```
mkdir -p $OOZIE_TMP_DIR;
chown -R $OOZIE_USER:$HADOOP_GROUP $OOZIE_TMP_DIR;
chmod -R 755 $OOZIE_TMP_DIR;
```
```
mkdir /etc/oozie/conf/action-conf 
chown -R $OOZIE_USER:$HADOOP_GROUP $OOZIE_TMP_DIR;
chmod -R 755 $OOZIE_TMP_DIR;
```
where:
- $OOZIE_DATA is the directory to store the Oozie data. For example, /var/db/oozie.
- $OOZIE_LOG_DIR is the directory to store the Oozie logs. For example, /var/log/oozie.
- $OOZIE_PID_DIR is the directory to store the Oozie process ID. For example, /var/run/oozie.
- $OOZIE_TMP_DIR is the directory to store the Oozie temporary files. For example, /var/tmp/oozie.
- $OOZIE_USER is the user owning the Oozie services. For example, oozie.
- $HADOOP_GROUP is a common group shared by services. For example, hadoop.
