> LLAP cache is polluted by query-based compactor
> -----------------------------------------------

> Key: HIVE-22705
> URL: https://issues.apache.org/jira/browse/HIVE-22705

> One of the steps that query-based compaction does is the verification of ACID
> sort order by using the _validate_acid_sort_order_ UDF. This is a
> prerequisite before the actual compaction can happen, and is done by a [query
> that reads the whole table
> content|https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/txn/compactor/MajorQueryCompactor.java#L161-L167].
> This results in the whole table content being populated into the cache. The
> problem is that this content is not useful and will rather pollute the cache
> space, as it can never be used again: cache content binds to files (file IDs)
> that obviously will be changed in this case by compaction.
> I propose we disable LLAP caching in the session of query-based compaction's
> queries.
