-----------------------------
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.
