Subject Query failing in Hive 2.2
Date Fri, 19 Jan 2018 21:37:33 GMT
Hi All,

I have a table partitioned on a date column. We have changed the data type
of one of the field for the older partitions and the data type of the newer
partitions will remain the same as the table. When I tried to run a simple
Select query on the older partitions , the query is failing with the below
error :
