Chuck Connell commented on HIVE-2380:
-------------------------------------
I am trying to use this feature (BINARY columns) and I believe I have the
perfect use-case for it, but I am missing something.
Here is the background... I have some files that each contain just one logical
field, which is a binary object. (The files are Google Protobuf format.) I want
to put these binary files into a larger file, where each protobuf is a logical
record. Then I want to define a Hive table that stores each protobuf as one
row, with the entire protobuf object in one BINARY column. Then I will use a
custom UDF to select/query the binary object.
This is about as simple as can be for putting binary data into Hive. But all of
the test cases for this jira seem to draw the binary columns from another
existing table and CAST them. I want to load the files from disk.
What file format should I use to package the binary rows? What should the Hive
table definition be? I cannot use TEXTFILE, since the binary may contain
newlines. Many of my attempts have choked on the newlines.
Thanks very much,
Chuck Connell
