Description

In the previous PR: https://github.com/apache/samza/pull/1010/files

config with null/empty values will be filter out when reading the coordinator stream, this will cause some problems when the user expects an empty string to be a value config.

 

Some user may expect configs with null value to be valid as well, we will not fix this part for now since when reading from coordinator stream, the job runner can't differentiate the null value generated from delete or update.
