Harsh J updated HADOOP-7328: ---------------------------- Attachment: HADOOP-7328.r7.diff Reupping trunk patch to get test-patch to go properly. Looks like it picked the wrong name :( > When a serializer class is missing, return null, not throw an NPE. > ------------------------------------------------------------------ > > Key: HADOOP-7328 > URL: https://issues.apache.org/jira/browse/HADOOP-7328 > Project: Hadoop Common > Issue Type: Improvement > Components: io > Affects Versions: 0.20.2 > Reporter: Harsh J > Assignee: Harsh J > Labels: io, serialization > Fix For: 0.23.0 > > Attachments: 0.22-HADOOP-7328.r7.diff, 0.23-HADOOP-7328.r7.diff, > HADOOP-7328.r1.diff, HADOOP-7328.r2.diff, HADOOP-7328.r3.diff, > HADOOP-7328.r4.diff, HADOOP-7328.r4.diff, HADOOP-7328.r5.diff, > HADOOP-7328.r6.diff, HADOOP-7328.r7.diff > > > When you have a key/value class that's non Writable and you forget to attach > io.serializers for the same, an NPE is thrown by the tasks with no > information on why or what's missing and what led to it. I think a better > exception can be thrown by SerializationFactory instead of an NPE when a > class is not found accepted by any of the loaded ones. -- This message is automatically generated by JIRA.
