> In the Namenode UI we have a text box to enter the chunk size.
> The expected value for the chunk size is a valid Integer value.
> If any invalid value, string or empty spaces are provided it throws number format exception.
> The existing behaviour is like we need to consider the default value if no value is specified.
> Soln
> ====
> We can handle numberformat exception and assign default value if invalid value is specified.
