Sorry, looks like you had already mentioned the hive version.
Hive 2.1.1 and Hive 1.1.0-cdh5.15.1

Hmmm, Looks like the query does filter on partition field.
Not sure why Hive is passing the partition_columns.
BTW, Which version of hive are you using ?
Also, while the query succeeds, Does the count (and result in general) looks
correct ?
Anyways, AbstractRealtimeRecordReader comes into picture only when reading
records from a split. The the partition projection/pruning outside of this
class (in hive). So, this should be ok.

Hi Balaji,
Sorry for late response.
I used this query to test:select count(*), par, dashboard_id from
dev.statistics_dashboard_visitor_hudi_rt where id = 20190 and par = '20190226'
group by dashboard_id ;
Thanks,Frank

Hi Kaka,
I see. The output of "describe formatted <table>" formatting got messed up in
the email and I missed the partitioning column.
Curious, How the query looks like. Is this a hive query ? Can you paste it ?

Hi Balaji,
Thanks. But the table I used is partitioned by par. It cannot been
distinguished.
Thanks,
Kaka
