Description

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.
