Arpit Agarwal commented on HDFS-5778:
-------------------------------------

The documentation looks really good. Generated a staging site and verified content/formatting.

Couple of typos:
# normoally --> normally
# "It may incur cluster downtime for upgrading JNs and ZKNs." --> "Upgrading JNs and ZKNs may incur cluster downtime".

+1 with these fixes.

> "hdfs dfsadmin -rollingUpgrade" command was newly added in HDFS-5752, and some other commands and parameters will be added in the future. This issue exists to flag undocumented commands and parameters when HDFS-5535 branch is merging to trunk.
