Mustafa Iman commented on HIVE-20359:
-------------------------------------

[~dlavati] I think we can we leave hbase-handler at old version and upgrade the 
rest of the system.

Protobuf2 Generated classes are not guaranteed to be compatible with protobuf3 
runtime 
([https://groups.google.com/forum/#!topic/protobuf/AwJlDT8ZWjQ)|https://groups.google.com/forum/#!topic/protobuf/AwJlDT8ZWjQ).]
 So we need to re-compile the proto files with protobuf3. Luckily wire format 
of protobuf 2 and 3 are compatible. Only thing is we need to relocate protobuf3 
dependency in hive to prevent classpath issues.

> The following protoc version's used in hive is very old i.e. 2.5.0 
> [https://repo.maven.apache.org/maven2/com/google/protobuf/protoc/] .  The 
> v2.5.0 does not have aarch64 support. But the AArch64 support started from 
> v3.5.0 on-words in google's protobuf project release.  The hive release 
> version branch v3/3.0/3.1/master branch build fails on AArch64 because of old 
> protoc version 2.5.0, in which there is no AArch64 support/exe available.
> After I replaced to latest available protoc version 3.6.1 the hive master 
> branch pom.xml files, The hive compiled without any issues on ARM64 machine.  
> This Jira ticket is used to propose a patch on Hive mailing list 
> [https://git.linaro.org/people/naresh.bhat/apache/hive.git/]  to update 
> pom.xml files protobuf version.  I will also cherry-pick patches for other 
> branches v3/3.0/3.1, and create a pull request.
