Adding the SAS Embedded Process to Nodes after the Initial Deployment

After the initial deployment of the SAS Embedded Process, additional nodes might be added to your cluster or nodes might need to be replaced. In these instances, you can install the SAS Embedded Process on the new nodes.

Follow these steps:

Log on to HDFS.
```
sudo su - root
su - hdfs | hdfs-userid
```
Note: If your cluster is secured with Kerberos, the HDFS user must have a Kerberos ticket to access HDFS. This can be done with kinit.
Navigate to the /sas/ep/config/ directory on HDFS.
Remove the ep-config.xml file from HDFS.
```
cd /sas/ep/config/
hadoop fs -rm ep-config.xml
```
Run the sasep-admin.sh script and specify the nodes on which you want to install the SAS Embedded Process.
```
cd EPInstallDir/SASEPHome/bin/
./sasep-admin.sh -add -hostfile host-list-filename | -host <">host-list<">
```
