Fengdong Yu commented on YARN-1696:
-----------------------------------
The document is really good.
two minor comments:
{code}
+ another RM is automatically elected to be the Active and takes over. Note
+ that, there is no need to run a separate ZKFC daemon as is the case for
+ HDFS.
{code}
A little bit unclear, we cannot suppose HDFS HA is enabled. so It can be "Not
that, RM automatic failover share ZKFC with HDFS if your HDFS HA enabled, so
there is no need to run a separate ZKFC daemon here."
{code}
+** Web Services
+
+ The web services automatically redirect to the Active.
{code}
web services are too general, It could be confused for a new Yarner. so just
changed to "RM web UI services" or some meaningful others.
