Description

This is similar issue as reported on AMBARI-22417, but for service checks.

The original issue of ambari check is resolved. But the same issue is seen when running the HDFS balancer via Ambari.

Solution
MD5 is disabled on the OS, Code needs to be updated to use SHA

This is required when FIPS mode is enabled on the RHEL OS
