Hi @kasius63,
a Hive table must exist that has that Parquet file in its location. Then Radoop can use it as an input, the file format does not matter.
(For efficiency, the default file format in Radoop Nest can be changed to Parquet as well if that is not the default already in Hive.)
Best,
Peter
Hi @kasius63,
the usual Retrieve from Hive operator should do it. You might need to turn the default file format in the Radoop Nest to Parquet, but i think this is rather for writing.
