Exception encountered during startup - Emptied cassandra.yaml file

Am using Cassandra 2.1.13 As part of some execution when C* was actually starting up and while C* start process was not complete, in mid of this operation the machine got rebooted. Strangely the C* configuration file cassandra.yaml is emptied when checked later and following exception seen.

Is it because of emptied conf file cassandra.yaml with no contents or the following exception did result in emptying the cassandra.yaml file?

Have you verified cassandra.yaml filr from standard config file without any changes? it seems some syntax error.
