No partition predicate found for Alias even when the partition predicate in present in the query

I have a table pos.pos_inv in hdfs which is partitioned by yyyymm. Below is the query:

select DATE_ADD(to_date(from_unixtime(unix_timestamp(Inv.actvydt, 'MM/dd/yyyy'))),5), to_date(from_unixtime(unix_timestamp(Inv.actvydt, 'MM/dd/yyyy'))),yyyymm from pos.pos_inv inv INNER JOIN pos.POSActvyBrdg Brdg ON Brdg.EIS_POSActvyBrdgId = Inv.EIS_POSActvyBrdgId where to_date(from_unixtime(unix_timestamp(Inv.nrmlzdwkenddt, 'MM/dd/yyyy'))) BETWEEN DATE_SUB(to_date(from_unixtime(unix_timestamp(Inv.actvydt, 'MM/dd/yyyy'))),6) and DATE_ADD(to_date(from_unixtime(unix_timestamp(Inv.actvydt, 'MM/dd/yyyy'))),6) and inv.yyyymm=201501 

I have provided the partition value for the query as 201501, but still i get the error"

 Error while compiling statement: FAILED: SemanticException [Error 10041]: No partition predicate found for Alias "inv" Table "pos_inv" 

(schema)The partition, yyyymm is int type and actvydt is date stored as string type.

This happens because hive is set to strict mode. this allow the partition table to access the respective partition /folder in hdfs .

 set hive.mapred.mode=unstrict; it will work 

In your query error it is said: No partition predicate found for Alias "inv" Table "pos_inv".

So you must put the where clause for the fields of the partitioned table (for pos_inv), and not for the other one (inv), as you've done.

set hive.mapred.mode=unstrict allows you access the whole data rather than the particular partitons. In some case read whole dataset is necessary, such as: rank() over

This happens when the 2 tables have the same column name (possibly same partition column). Try to deal with separate tables with where condition like below

WITH tableA as ( -- All your where clause here ), tableB AS ( -- All your where clause here ) select tableA.*, tableB.*
