2. Set Directories and Permissions

Create directories and configure ownership + 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:

Recommended - Edit and source the files included in scripts.zip file (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;
```
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.
