Hello Apologies for the silly question.
What you say "MM tables", what does MM stand for?
HIVE_MM_ALLOW_ORIGINALS("hive.mm.allow.originals", false, "Whether to allow original files in MM tables. Conversion to MM may be expensive if\n" + "this is set to false, however unless MAPREDUCE-7086 fix is present (hadoop 3.1.1+),\n" + "queries that read non-orc *MM tables* with original files will fail. The default in\n" + "Hive 3.0 is false."),
thank you Gabriel Balan P.S. And since I'm already showing my ignorance, I've also seen these mentioned: * DP tables <https://issues.apache.org/jira/secure/attachment/12833236/HIVE-14643.patch> (dynamic partitions?) * SMB table <https://issues.apache.org/jira/browse/HIVE-20620> (sort merge bucket?) -- The statements and opinions expressed here are my own and do not necessarily represent those of Oracle Corporation.
