Jinfeng Ni commented on DRILL-4339:
-----------------------------------
If the storage plugin has subclass of AbstractRecordReader, I think the plugin
has to recompile.
Are we supposedly going to keep this not-required-for-recompile for storage
plugin with each new release?
Actually, I just realized this method's signature does not have to change at
all ( Maybe I had to change it because of other codes which are not included in
the patch, but I forgot to change it back). I can change it back to the
original signature of setColumns().
