Because Arm Treasure Data is a cloud-based hosting environment, the platform has certain constraints that do not exist in a local Hadoop setup. These constraints ensure that your app takes advantage of Treasure Data’s scalability and redundancy features.
Hive User-Defined Functions (UDF)
Although Treasure Data supports default Hive UDFs and Treasure Data-specific UDFs (see Supported UDFs), custom Hive UDFs cannot be added. If you have a specific request for a function, please let us know.
Hive Custom Map/Reduce Scripts
Custom Map/Reduce scripts cannot be used due to security considerations.
