Alan Gates updated PIG-2645: ---------------------------- Resolution: Fixed Fix Version/s: 0.11 Status: Resolved (was: Patch Available) Fix checked into trunk and branch. Thanks Shami. > PigSplit does not handle the case where SerializationFactory returns null > ------------------------------------------------------------------------- > > Key: PIG-2645 > URL: https://issues.apache.org/jira/browse/PIG-2645 > Project: Pig > Issue Type: Bug > Components: impl > Affects Versions: 0.10.0 > Reporter: Alex Levenson > Assignee: Shami B > Labels: patch > Fix For: 0.11 > > Attachments: patch_2645.patch, PIG-2645.patch > > > In PigSplit.java, line 254: > {code} > SerializationFactory sf = new SerializationFactory(conf); > Serializer s = sf.getSerializer(wrappedSplits[0].getClass()); > s.open((OutputStream) os); > {code} > sf.getSerializer returns null when it cannot find a serializer for a given > object. Instead of handling this properly, a NPE is thrown when s.open() is > called. > This is easy to encounter when creating a custom InputSplit from the > mapreduce package which is an abstract class that DOES NOT implement Writable. > However it's easy to miss because InputSplit from the mapred package is an > interface that extends Writable, and InputSplits often both extend and > implement both the new and old InputSplit abstract class and interface > (thereby becoming Writable). -- This message is automatically generated by JIRA.
