Summary: Document Fix for
yarn.app.mapreduce.client-am.ipc.max-retries

URL: https://issues.apache.org/jira/browse/MAPREDUCE-7425
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: yarn
Affects Versions: 3.3.4
Reporter: teng wang
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)
{code:java}
// mapred-default.xml
<property>
<name>yarn.app.mapreduce.client-am.ipc.max-retries</name>

+ 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> {code}
