Jonathan Eagles commented on MAPREDUCE-3185:
--------------------------------------------
The default row limit for switching to JSON vs HTML is 100 rows. You can
specify the rowlimit URL param to override the default.
For Example
<machine>:<port>/cluster/apps?rowlimit=1
> RM Web UI does not sort the columns in some cases.
