> Steps to reproduce:
> Create a table with import:
> {{CREATE TABLE temp_acid(id string, value string) CLUSTERED BY(id) INTO 10 BUCKETS STORED AS ORC TBLPROPERTIES('transactional'='true');}}
> {{insert into temp_acid values ('1','one'),('2','two'),('3','three'),('4','four'),('5','five'),('6','six'),('7','seven'),('8','eight'),('9','nine'),('10','ten'),('11','eleven'),('12','twelve'),('13','thirteen'),('14','fourteen'),('15','fifteen'),('16','sixteen'),('17','seventeen'),('18','eighteen'),('19','nineteen'),('20','twenty');}}
> {{}}
> {{export table temp_acid to '/tmp/temp_acid';}}
> {{{}i{}}}{{{}mport table imported from '/tmp/temp_acid';{}}}
> If the data is loaded or imported into the table they way it is described above, the rows in the ORC file don't contain the ACID metadata. The query-based MINOR compaction fails on this kind of table, because when the FileSinkOperator tries to read out the bucket metadata from the rows it will throw a NPE. But deleting and updating a table like this is possible. So somehow the bucketId can be calculated for rows like this.
> The non-query based MINOR compaction works fine on a table like this.
