Chris Li updated GOBBLIN-1055:
------------------------------
Description:
When state.store.enabled=true and state.store target is on HDFS, Gaas flows run
into error when writing job state. The reason is that Gaas used a particularly
GobblinClassLoader to load classes, and without giving that information to
Hadoop Configuration, the Hadoop hook tries to load the custom serializer using
default Class Loader.
See stack trace in comments. While *WritableShimSerialization* was loaded
successfully by GobblinClassLoader, Hadoop is not able to find it through
default Class Loader.
