Shalin Shekhar Mangar commented on SOLR-974:
--------------------------------------------

bq. I guess the best thing is to expose the 'stats' as a variable in DIH. This can also be exposed through the Context#getStats() 

I like this idea. I'll give a patch.

> The DataImportHandler always finishes an import with a commit, even if it retrieved no data from its data source. Add a short circuit to not commit if no data was imported.
