Harsh J updated HDFS-4259:
--------------------------
Attachment: HDFS-4259.patch
Here's a patch that changes it to:
bq. Failed to replace a bad datanode on the existing pipeline due to no more
good datanodes being available to try. (Nodes: current=[foo], original=[bar]).
The current failed datanode replacement policy is Y, and a client may configure
this via 'X.policy' in its configuration.
> Improve pipeline DN replacement failure message

> bq. Failed to add a datanode. User may turn off this feature by setting
> X.policy in configuration, where the current policy is Y. (Nodes:
> current=[foo], original=[bar])
> This reads off like failing is a feature (but the intention and the reason we
> hit this isn't indicated strongly), and can be bettered.
