> Llap external client gives different precision/scale as compared to when the
> query is executed beeline. Consider the following results:
> Query:
> {code}
> select avg(ss_ext_sales_price) my_avg from store_sales;
> {code}
> Result from Beeline
> {code}
> +----------------------------+
> | my_avg |
> +----------------------------+
> | 37.8923531030581611189434 |
> +----------------------------+
> {code}
> Result from Llap external client
> {code}
> +---------+
> | my_avg|
> +---------+
> |37.892353|
> +---------+
> {code}
>
> This is due to Driver(beeline path) calls
> [analyzeInternal()|https://github.com/apache/hive/blob/rel/release-3.1.1/ql/src/java/org/apache/hadoop/hive/ql/parse/CalcitePlanner.java#L328]
> for getting result set schema which initializes
> [resultSchema|https://github.com/apache/hive/blob/rel/release-3.1.1/ql/src/java/org/apache/hadoop/hive/ql/parse/SemanticAnalyzer.java#L333]
> after some more transformations as compared to llap-ext-client which calls
> [genLogicalPlan()|https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/parse/ParseUtils.java#L561]
> Replacing {{genLogicalPlan()}} by {{analyze()}} resolves this.
