Panagiotis Garefalakis updated ORC-696:
---------------------------------------
Description:
SARGs mapping can fail expecting a sanitized quoted colName (parseName utility
function):
https://github.com/apache/orc/blob/master/java/core/src/java/org/apache/orc/impl/ParserUtils.java#L255
This PR makes sure fieldNames are consistent as part of convertTypeFromProtobuf
method.
was:
Parsing TypeDescription from a String currently sanitizes quoted names using
the parseName utility function:
https://github.com/apache/orc/blob/master/java/core/src/java/org/apache/orc/impl/ParserUtils.java#L164
However, this step can be skipped if the schema is created directly using:
*TypeDescription.createStruct().addField() *
As a result, find Sargs mapping can fail expecting a sanitized internal
colName:
https://github.com/apache/orc/blob/master/java/core/src/java/org/apache/orc/impl/ParserUtils.java#L255
This PR makes fieldNames consistent as part of convertTypeFromProtobuf method.
