> If you hoover mouse over Data per Reducer at Customize Services of CLUSTER INSTALL WIZARD,
the following message explains what 'Data per Reducer' is as shown in the screenshot:
> "size per reducer. The default is 256 Mb, i.e if the the input size is 1G, it will use
4 reducers".
> Since the default value is 64 MB on slider, it is not so clear at first why the message
says 'the default is 256 Mb'. We can add something like '64 MB x 4 reducers' to make it more
clear.
