Easier Decimal datatype mapping in HCATALOG

Currently, we have to map the DECIMAL(x,y) of HDFS DATA TYPE to STRING of HCATALOG DATA TYPE. Everytime value of x & y changes, we have to add a new data type mapping. This is not a feasible way of handling data type mapping between HDFS and HCATALOG.

“Administration > Map Data Types page“

User needs a more easy way where mapping should be defined only once Eg: DECIMAL ---> STRING and it should work for all precision of Decimal i.e. decimal (x,y)

Customer Impact Major inconvenience

    Request: ability to set a default for DECIMAL(x,y) where there is not already a mapping defined, for example, DECIMAL(6,2), to the specified destination (e.g. STRING)
