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>
