[jira] [Created] (HDFS-4259) Improve pipeline DN replacement
failure message
Harsh J created HDFS-4259:
-----------------------------
Summary: Improve pipeline DN replacement failure message
Key: HDFS-4259
URL: https://issues.apache.org/jira/browse/HDFS-4259
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs-client
Affects Versions: 2.0.2-alpha
Reporter: Harsh J
Priority: Minor
The current message shown is something such as below:
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.

--------------------------------------
+1, the patch looks good to me. I agree that this is an improvement to the error message that should hopefully decrease confusion when folks see it.

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.
