----------------------------------
Summary: Hive Serdes Should Handle Null Strings Consisently
Key: HIVE-17992
URL: https://issues.apache.org/jira/browse/HIVE-17992
Project: Hive
Issue Type: Bug
Reporter: Shawn Weeks
Priority: Minor
The various text based serdes handle empty strings and null differently. All of
them should honor serialization.null.format or another similar mechanism.
Currently the default text SerDe and MultiDelimitSerDe conform to the parameter
while the RegexSerDe and OpenCSVSerde do not. This leads to awkward filter
clauses where you have to remember to both check for null and empty string.
