      Work Description: iemejia commented on issue #9779: [BEAM-8388] Updating 
avro dependency from 1.8.2 to 1.9.1
URL: https://github.com/apache/beam/pull/9779#issuecomment-541557410
 
 
   [BEAM-7328](https://issues.apache.org/jira/browse/BEAM-7328) (the previous 
issue to migrate to Avro 1.9.x) ended up being 'stalled' for two reasons still 
worth to consider in this PR:
   
   1. Potential compatibility issues for Beam Java users given that Avro is 
transitively 'leaked' as part of Core SDK public API. This is the same issue 
for any 'transitive' dependency we offer on Beam (e.g. Jackson), but there may 
be some minor issues for users because of Avro API changes, remember Avro minor 
versions are not backwards compatible code-wise (but they are format-wise). 
Anyway migrating is good for multiple other reasons like security fixes, but we 
probably should warn or discuss on the consequences of this on the ML.
   
   2. Issues on target runners where Avro 1.9.x has not been downstreamed. More 
concretely Spark runner core module depends still on Avro 1.8.x (AFAIK Spark 
runner does not use Avro at all, but maybe Spark core does) so we should 
probably as part of this PR guarantee that all the Spark related tests pass 
too).
