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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
