During Mammoth Upgrade for example a 4.5 to 4.8 upgrade, upgrade fails because, "Maximum Non-Java Memory of Service Monitor" gets reset to 0 from the existing value. The existing value can be the default or a custom setting.

The sequence leading to this is:

1. Upgrade fails and Cloudera Manager shows the Cloudera Management Service (mgmt) is in bad health.  See:

2. Drilling down shows that the problem is due to "Maximum Non-Java Memory of Host Monitor". The error looks like:

mgmt: Maximum Non-Java Memory of Host Monitor
Could not parse: Maximum Non-Java Memory of Host Monitor: Could not parse parameter 'firehose_non_java_memory_bytes'. Was expecting a long
numeric value. Input.


3. Navigating

Navigating in CM: mgmt > Instances > Service Monitor > Configuration > Search: Maximum Non-Java Memory of Service Monitor, shows that instead of the default value or custom value, the value is incorrectly set to "0" GB.
