> Project: Hive
> Issue Type: Bug
> Reporter: Vikram Ahuja

> Priority: Major

> Fix For: 4.0.0

>
> Hive.getAllPartitionsOf() tries to list partitions in one go, it can cause
> memory related issues with wide tables(>2000 columns) with large amount of
> partitions when data is being transferred from HMS to HS2 using Thrift.
> Optimise the flow to use PartitionIterable so that partitions can be fetched
> in batches rather than one go.
