> Support displaying complex types

>
> Key: IMPALA-9494
> URL: https://issues.apache.org/jira/browse/IMPALA-9494
> Project: IMPALA
> Issue Type: Epic
> Components: Backend, Frontend
> Reporter: Gabor Kaszab
> Assignee: Gabor Kaszab
> Priority: Major
> Labels: complextype
>
> Currently displaying complex types is not supported in Impala. There is a
> workaround to see the unnested content of the collections but there is no
> such functionality to display one complex type in one result column formatted
> to Json. Note, Hive does have support for the same.
> The scope of this Jira is to have an umbrella for the following tasks:
> - Support all complex types (Struct, Array, Map) in the SELECT list and
> display them as Json.
> - Display complex type columns in Json for a "SELECT *" query
> - Allow returning complex types in a sub-select
> - Have the display support for Parquet and ORC
> Note, I made the sub-tasks as small as possible so that this granularity
> allows to parallelise the work.
