----------------------------
Summary: The error message is not friendly when set a path with
the policy not enabled
Key: HDFS-12087
URL: https://issues.apache.org/jira/browse/HDFS-12087
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs
Affects Versions: 3.0.0-alpha3
Reporter: lufei
Assignee: lufei
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}
