DFSClient read fails: "Read failure for X copy locations"... "createRemoteActivity: unathorized"

• DFSClient actions are reliant on properly configured "ClusterGroup" Keys on the target HPCC Systems cluster.
• User should contact the HPCC cluster admin and ensure the Keys section is correctly configured
• Sample Keys configuration element:

<Keys>
    <ClusterGroup keyPairName="mythor" name="mythor"/>
    <ClusterGroup keyPairName="mythor" name="myroxie"/>
    <ClusterGroup keyPairName="mythor" name="hthor__myeclagent"/>```
    <KeyPair name="mythor" privateKey="/home/hpcc/certificate/key.pem" publicKey="/home/hpcc/certificate/public.key.pem"/>
</Keys>

• Common issues include: Invalid keypairs, inconsistent keypairs across all nodes, invalid keypair paths, no keypair associated with target ClusterGroup
