### Description of PR
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
