zenfenan commented on issue #11474: FLINK-10114: Add ORC BulkWriter support for 
StreamingFileSink
URL: https://github.com/apache/flink/pull/11474#issuecomment-614053436
 
 
   Yes, @kl0u 
   
   I am moving the codebase to `flink-orc` but before that I think we need to 
bump ORC dependency version to 1.5.6. Reason why I'm stressing on 1.5.6 is: 
   
   1. It is the version I have used in this PR. Haha.. Anyway, if we still want 
to keep the ORC version as is (i.e. 1.4.3), there will be some code change in 
the `PhysicalFsWriterImpl`.
   2. 1.4.3 which is used in the project is little outdated so it makes sense 
to use this as an opportunity to upgrade to an even newer and stable version.
   3. 1.6.x is not being used anywhere majorly, AFAIK. Even Hive 3.x is using 
ORC 1.5.6 as the dependency.
   
   Having said that, I have created a 
[Jira](https://issues.apache.org/jira/browse/FLINK-17142) to bump the ORC 
dependency version to 1.5.6. I did the change locally and tested the flink 
build with and everything is good so I have just raised a PR #11759. I suggest 
we merge that first and then this PR.
   
   What do you think?
