The hdfs installation fails with the following error while installing cdh 6.2.
Can't open /var/run/cloudera-scm-agent/process/63-hdfs-NAMENODE-format/supervisor_status:Permission denied
what would cause this error?

The error message regarding the supervisor_status file can be ignored. We will fix the code that generates that error sometime in the future.
The message that indicates the cause of the formatting failure is:
Running in non-interactive mode, and data appears to exist in Storage Directory /dfs/nn.
Not formatting.
It may be you have some old data in /dfs/nn. If you are sure you do not need what is in /dfs/nn you can copy it to another location or delete it. Just be sure you don't need/want whatever is there.
