> First user add a policy by -addPolicies command but not enabled, then user
> set a path with this policy. The error message displayed as below:
> {color:#707070}RemoteException: Policy 'XOR-2-1-128k' does not match any
> enabled erasure coding policies: []. The set of enabled erasure coding
> policies can be configured at 'dfs.namenode.ec.policies.enabled'.{color}
> The policy 'XOR-2-1-128k' is added by user but not be enabled.The error
> message is not promot user to enable the policy first.I think the error
> message may be better as below:
> {color:#707070}RemoteException: Policy 'XOR-2-1-128k' does not match any
> enabled erasure coding policies: []. The set of enabled erasure coding
> policies can be configured at 'dfs.namenode.ec.policies.enabled' or enable
