> Jobs with large number of tasks can have job history files that are large in size and
resource-consuming(mainly memory) to parse in Job History Server. If there are many such jobs,
the job history server can very easily hang.
> It would be a good usability feature if we added a new config property that could be
set to X, where the JHS wouldn't load the details for a job with more than X tasks. The job
would still show up on the list of jobs page, but clicking on it would give a warning message
that the job is too big, instead of actually loading the job. This way we can prevent users
from loading a job that's way too big for the JHS, which currently makes the JHS hang. The
default value can be -1 so that it's disabled.
