Description

The document of yarn.app.mapreduce.client-am.ipc.max-retries and yarn.app.mapreduce.client-am.ipc.max-retries-on-timeouts is not detailed and complete. yarn.app.mapreduce.client-am.ipc.max-retries is used to overwrite ipc.client.connect.max.retries in ClientServiceDelegate.java. So, the document is suggested to fix as: (refer to yarn.client.failover-retries)

 

// mapred-default.xml
<property>
  <name>yarn.app.mapreduce.client-am.ipc.max-retries</name>
  <value>3</value>
  <description>The number of client retries to the AM - before reconnecting
-    to the RM to fetch Application Status.</description>
+    to the RM to fetch Application Status. 
+    In other words, it is the ipc.client.connect.max.retries to be used during
+    reconnecting to the RM and fetching Application Status.</description>
</property>
