> 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 the policy by '-enablePolicy' EC command before.{color}
