> When a single row is too large for the RS heap then an OOME can take out the
> entire RS. Setting scanner batching in custom scans helps avoiding this
> scenario, but for the supplied Export job this is not set.
> Similar to HBASE-3421 we can set the batching to a low number - or if needed
> make it a command line option.
