Tomo Suzuki updated BEAM-9144:

Description:

{quote}My org must use Avro 1.9.x (due to some Avro schema resolution issues
resolved in 1.9.x) so downgrading Avro is not possible for us.
Beam 2.16.0 is compatible with our usage of Avro 1.9.x – but upgrading to
2.17.0 we are broken as 2.17.0 links to Java classes in Avro 1.8.x that are not
available in 1.9.x.
{quote}
The Java class is {{org.apache.avro.data.TimeConversions.TimestampConversion}}
in Avro 1.8.
It's renamed to {{org.apache.avro.data.JodaTimeConversions}} in Avro 1.9.
# Beam Java SDK cannot upgrade Avro to 1.9
Beam has Spark runners and Spark has not yet upgraded to Avro 1.9.
Illustration of the dependecy

# Short-term Solution
As illustrated above, as long as Beam Java SDK uses only the intersection of
Avro classes, method, and fields between Avro 1.8 and 1.9, it will provide
flexibility in runtime Avro versions (as it did until Beam 2.16).
