Takanobu Asanuma commented on HDFS-8238:
----------------------------------------
I investigated the cause of the error about
{{TestSafeMode#testOperationsWhileInSafeMode}}. And I found that the signiture
of {{SafeModeException(String msg)}} broke dependencies. It occors in the try
block in {{RemoteException#unwrapRemoteException}}. So we should change the
signiture. Other codes look good to me.
> Move ClientProtocol to the hdfs-client

> The {{ClientProtocol}} class defines the RPC protocol between the NN and the
> client. This jira proposes to move it into the hdfs-client module.
> The jira needs to move:
> * {{o.a.h.hdfs.server.namenode.SafeModeException}} and
> {{o.a.h.hdfs.server.namenode.NotReplicatedYetException}} to the hdfs-client
> package
> * Remove the reference of {{DistributedFileSystem}} in the javadoc
> * Create a copy of {{DFSConfigKeys.DFS_NAMENODE_KERBEROS_PRINCIPAL_KEY}} in
> {{HdfsClientConfigKeys}}
