> The root cause is the method `getErasureCodingPolicy` was introduced in
> hadoop 3 and the method signature is different to mock fs of
> TestECPolicyDisabler. Fortunately, all we want to test is the static method
> 'ECPolicyDisabler#check' so we can add a new argument to make it be able to
> check another method.
