Subject [jira] [Commented] (MRUNIT-157) allow null keys and values as output, expected output
Date Thu, 11 Jul 2013 19:39:48 GMT


Prashant Kommireddi commented on MRUNIT-157:

Hey guys - is this something that should be/will be fixed? We are moving from 0.20.1+152 to
1.0.0. Adding null as key worked in the former but throws a NPE in the latter version. 

Is there a workaround? How are nulls handled?

> Hadoop allows null keys and values, when not used as intermediate keys,values between
mappers and reducers. MRUnit should also allow allow null keys and values as output and expected
output. The Serialization class will need to be modified to not try to copy null's into the
output, expected output
