> Key: HIVE-3396
> URL: https://issues.apache.org/jira/browse/HIVE-3396
> Project: Hive
> Issue Type: Bug
> Components: Statistics
> Affects Versions: 0.10.0
> Reporter: Kevin Wilfong

>
> 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';
