-----------------------------------
Summary: Provide different timeout settings for hdfs dfsadmin
-getDatanodeInfo.
Key: HDFS-8510
URL: https://issues.apache.org/jira/browse/HDFS-8510
Project: Hadoop HDFS
Issue Type: Improvement
Components: tools
Reporter: Chris Nauroth
Assignee: Chris Nauroth
During a rolling upgrade, an administrator runs {{hdfs dfsadmin
-getDatanodeInfo}} to check if a DataNode has stopped. Currently, this
operation is subject to the RPC connection retries defined in
{{ipc.client.connect.max.retries}} and {{ipc.client.connect.retry.interval}}.
This issue proposes adding separate configuration properties to control the
retries for this operation.
