I am using PostgreSQL for the Cloudera Manager Server and other services that use databases. I'm using a RHEL 7.4 Azure VM and following the official documentation -https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/prepare_cm_database.html I have completed step 4(Install Databases). In Step 5 : Set up the Cloudera Manager Database, on executing the scm_prepare_database.sh script I'm getting the following output- [root@machine1 ~]# sudo /opt/cloudera/cm/schema/scm_prepare_database.sh postgresql scm scm
Enter SCM password:
JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera
Verifying that we can write to /etc/cloudera-scm-server
Creating SCM configuration file in /etc/cloudera-scm-server
