Danny Chen updated HUDI-9573:
-----------------------------
Description:
Currently we see a few type casting errors in a few places:
{code:java}
org.apache.hudi.common.table.timeline.versioning.v2.CommitMetadataSerDeV2.deserialize(CommitMetadataSerDeV2.java:88)
at
org.apache.hudi.common.table.timeline.HoodieTimeline.readNonEmptyInstantContent(HoodieTimeline.java:153)
at
org.apache.hudi.common.table.timeline.HoodieTimeline.readRollbackPlan(HoodieTimeline.java:244)
at
org.apache.hudi.metadata.HoodieTableMetadataUtil.getRollbackedCommits(HoodieTableMetadataUtil.java:2034)
... 30 more
Caused by: java.lang.ClassCastException: class
org.apache.avro.generic.GenericData$Record cannot be cast to class
org.apache.avro.specific.SpecificRecordBase
(org.apache.avro.generic.GenericData$Record and
org.apache.avro.specific.SpecificRecordBase are in unnamed module of loader
'app'){code}
The reason is some JDK releases does now allow type coersion for instantces
from different classloaders,
see issue https://github.com/apache/hudi/issues/13410 for more details.
