Chris Nauroth created HDFS-8510:
-----------------------------------

             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.
