Vihang Karajgaonkar commented on HIVE-21586:
--------------------------------------------
[~ngangam] [~pvary] Can you please take a look? There is no code change
involve. The patch just rearranges certain struct definitions such that they
are defined before they are used.
> Thrift generated cpp files for metastore do not compile

> Key: HIVE-21586
> URL: https://issues.apache.org/jira/browse/HIVE-21586
> Project: Hive
> Issue Type: Bug
> Components: Standalone Metastore
> Affects Versions: 3.1.0
> Reporter: Vihang Karajgaonkar
> Assignee: Vihang Karajgaonkar
> Priority: Major
> Attachments: HIVE-21586.01.patch, HIVE-21586.nothrift.patch
>
>
> The way some structs like CreationMetadata, CompactionInfo, ColumnStatistics
> are defined in hive_metastore.thrift is that these structs are used before
> they are defined. While this works for the java code which is generated, it
> does not work for the generated cpp code since Thrift does not use
> pointer/references to the forward declared classes.
> The easy fix for this would be to reorder the struct definitions in the
> hive_metastore.thrift so that they are always defined before they are used.
