Junping Du updated HDFS-8510:
-----------------------------
Target Version/s: (was: 2.8.0)
> 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.
