> Compaction fails on non bucketed table with data loaded inpath

>                 URL: https://issues.apache.org/jira/browse/HIVE-22661
>             Project: Hive
>          Issue Type: Bug
>            Reporter: Ádám Szita
>            Assignee: Ádám Szita
>            Priority: Major

> Compaction cannot handle situations where:
>  * data was ingested with {{LOAD DATA INPATH}}
>  * this ingest method is run multiple times, and
>  ** with different number of files getting created in the delta directories
> Therefore, for file/dir structures such as:
> {code:java}
> /warehouse/tablespace/managed/hive/comp3/delta_0000001_0000001_0000
> /warehouse/tablespace/managed/hive/comp3/delta_0000001_0000001_0000/000000_0
> /warehouse/tablespace/managed/hive/comp3/delta_0000001_0000001_0000/000001_0
> /warehouse/tablespace/managed/hive/comp3/delta_0000002_0000002_0000
> /warehouse/tablespace/managed/hive/comp3/delta_0000002_0000002_0000/000000_0
> /warehouse/tablespace/managed/hive/comp3/delta_0000002_0000002_0000/000001_0
> /warehouse/tablespace/managed/hive/comp3/delta_0000002_0000002_0000/000002_0 {code}
> Although the table is not bucketed, bucket is calculated from the (raw) files' names. Compaction in the above case will fail on delta1-1 not having data for 'bucket' 2.
> Steps to repro using small dataset:
> {code:java}
> set tez.grouping.min-size=8;
> set tez.grouping.max-size=8;
> set mapreduce.input.fileinputformat.split.minsize=8;
> set mapreduce.input.fileinputformat.split.minsize=8;
> create external table comp0 (a string);
> insert into comp0 values ("qwertyuiopasdfghjklzxcvbnm");
> insert into comp0 values ("qwertyuiopasdfghjklzxcvbnm");
> create external table comp1 stored as orc as select * from comp0;
> insert into comp0 values ("qwertyuiopasdfghjklzxcvbnm");
> create external table comp2 stored as orc as select * from comp0;
> create table comp3 (a string);
> load data inpath '/warehouse/tablespace/external/hive/comp1' into table comp3;
> load data inpath '/warehouse/tablespace/external/hive/comp2' into table comp3;{code}
