Issue/Introduction

After execution digital_oi_installer_1.3.2_16.bin everything finished fine.

However not all PVs are in Bound state, doiproject-hadoop-data-0-pv has state Available.

Created Storage manually for that PV in Opehshift Console and state changed to Bound. 

However after DOI project was deployment few pods are not in running status:

 - Clientnodemanager is on stuck state,

 - Jobmanager failed to deploy. 

Messages in the install log (digital_oi_installer.log):

creating storage class doi-usage
Error from server (AlreadyExists): error when creating "docs/ca-digital-oi-storageclass.yaml": storageclasses.storage.k8s.io "doi-usage" already exists

Installer log (CA_digital_oi_1.3.2_Install_01_20_2020_01_10_49.log) seems to say everything was a success.
