> With the configs hive.stats.reliable and hive.stats.autogather are set to true, and using either the HBase or JDBC Stats Publishers, if a FileSinkOperator does not receive any rows, and hence collects no stats, it will throw an exception.
> Related, if hive.stats.reliable is set to false it will still log a warning which seems unnecessary.
> Repro:
> create table tmptable(key string, value string) partitioned by (part string);
> set hive.stats.autogather=true;
> set hive.stats.reliable=true;
> insert overwrite table tmptable partition (part = '1') select * from src where key = 'no_such_value';
