cloudera-scm-agent errors fails with large mounted filesystem

There seems to big an issue with the cloudera-scm-agent process where it will throw an AvroTypeException if there is a mount point on the host that has a HUGE amount of space.

On an AWS instance I have mounted an "Elastic File System" mount point ("/shared") which is an NFS mount. EFS reports back a huge amount of space (9007199170887680 bytes) which seems to be to big for the "validate" method used before creating the cord to send back to the heartbeat agent.

Example json blob that it is attempting to validate:

{'request': {'host_id': '953bdfd1-0b69-4869-9759-4b4d193f2614',
'host_stats': {'load_avg': [0.27, 0.34, 0.38],
'mountpoint_available_space_bytes':

{'/': 90046795776, '/data01': 902647525376, '/run': 1682300928, '/run/cloudera-scm-agent/process': 8396541952, '/run/lock': 5242880, '/run/shm': 8413761536, '/run/user': 104857600, '/shared': 9223371950988984320, '/sys/fs/cgroup': 4096}

,

If I umount this file system, everything starts to work again.
