Description

https://issues.apache.org/jira/browse/HIVE-21641 handles decimal scale/precision inconsistencies when we query using llap external client.

HIVE-21641 changes analyzer.genLogicalPlan(ast) to analyzer.analyze(ast, ctx) to handle this. However we should fix analyzer.genLogicalPlan(ast) to return correct decimal precision/scale.
Please see this and this comment for more.
