Resolution: Not A Problem
Affects Version/s: 0.13.0
Fix Version/s: None
Component/s: Query Processor
The Support for REGEX Column is OK in HIVE 0.12, but is broken in HIVE 0.13.
will fail in HIVE 0.13 with the following error from SemanticAnalyzer:
This issue is related to
HIVE-6037. When set "hive.support.quoted.identifiers=none", the issue will be gone.
I am not sure the configuration was intended to break regex column. But at least the documentation needs to be updated: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Select#LanguageManualSelect-REGEXColumnSpecification
I would argue backward compatibility is more important.
