> Make ParseContext::semanticInputs a map

>                 Key: HIVE-12308
>                 URL:

>          Issue Type: Bug
>            Reporter: Hari Sankar Sivarama Subramaniyan
> Follow up jira for HIVE-7723.  Explain plan for complex query with lots of partitions
is slow due to in-efficient collection used to find a matching ReadEntity. 
> As part of HIVE-7723, we will create a map during PlanUtils.addPartitionInputs(), we
should start with a map if possible in ParseContext::semanticInputs to save CPU burn on this
additional operation.
