Subject [jira] [Created] (ACCUMULO-2962) RangeInputSplit Writable methods don't serialize IteratorSettings
Date Mon, 30 Jun 2014 23:09:24 GMT
Josh Elser created ACCUMULO-2962:

             Summary: RangeInputSplit Writable methods don't serialize IteratorSettings
                 Key: ACCUMULO-2962
             Project: Accumulo
          Issue Type: Bug
          Components: client
    Affects Versions: 1.6.0, 1.5.1
            Reporter: Josh Elser
            Assignee: Josh Elser
            Priority: Critical
             Fix For: 1.5.2, 1.6.1, 1.7.0

Was trying to figure out why some information was getting lost on a RangeInputSplit after
serialization, and found out it was because the serialization and deserialization of the class
didn't include the configured IteratorSettings.

This likely isn't a big problem for normal users as, when no IteratorSettings are configured
on the RangeInputSplit, it falls back to pulling from the Configuration, but it's possible,
with "non-standard" uses of mapreduce, that information could be missing in the Configuration
that the mappers receive, and would subsequently error.
