Alessandro Solimando commented on HIVE-26691:
---------------------------------------------
+1 for mentioning in the release notes and in the wiki.
For upstream vs downstream, how do developers manage at the moment? On MacOS
with brew I have multiple versions installed, and I switch with _brew unlink_ +
{_}brew link{_}. This does not seem a problem to me.
For the frequency of the update, I don't think it really matters, the same line
of reasoning could apply for the JVM, mvn, etc., developers are required to
have a proper setup for compiling, adding or removing thrift to that does not
make a significant difference.
For protobuf I guess the situation it's similar, but I have never had to deal
with that.
> Generate thrift files by default at compilation time
> ----------------------------------------------------
>
> Key: HIVE-26691
> URL: https://issues.apache.org/jira/browse/HIVE-26691
> Project: Hive
> Issue Type: Task
> Components: Thrift API
> Affects Versions: 4.0.0-alpha-2
> Reporter: Alessandro Solimando
> Priority: Major
>
> Currently Hive does not generate thrift files within the main compilation
> task ({_}mvn clean install -DskipTests{_}), but it uses a separate profile
> ({_}mvn clean install -Pthriftif -DskipTests -Dthrift.home=$thrift_path{_}),
> and thrift-generated files are generally committed in VCS.
> Other Apache projects like Parquet
> ([https://github.com/apache/parquet-mr/blob/master/parquet-thrift/pom.xml)]
> use a different approach, building all thrift files by default in the main
> compilation task.
> In general, generated files should not be part of our VCS, only the "source"
> file should be (.thrift files here).
> Including generated files in VCS is not only problematic because they are
> verbose and clog PR diffs, but they also generate a lot of conflicts (even
> when the changes over the thrift file can be merged automatically).
> The ticket proposes to move the thrift files generation at compile time,
> remove the thrift-generated files from VCS, and add them to the "ignore" list.
