------------------------------------
Summary: Can't select from table after minor compaction of MM
table with original files
Key: HIVE-23072
URL: https://issues.apache.org/jira/browse/HIVE-23072
Project: Hive
Issue Type: Bug
Reporter: Karen Coppage
I'm assuming minor compaction shouldn't be run on tables containing original
files (==files outside a delta/base directory) in general because minor
compaction requires that the table have >1 delta directory (see
Worker#isEnoughToCompact). However, it is possible under the following
circumstance:
1. Create non-transactional table, stored as e.g. textfile or parquet (orc
doesn't have this problem)
2. Run a couple inserts -> creates original files
3. Alter table, make insert-only.
4. Run a couple inserts -> creates delta dirs
5. Run minor compaction.
The attached unit test recreates these steps and results in the error below [1].
Side notes:
If the table was insert-only from the beginning (no original files), then no
problem, the split examined/returned is:

{code}
I tried playing around with mapreduce.input.fileinputformat.input.dir.recursive
without success since it messes with the ability to ignore delta dirs that
shouldn't be read.
