Ferdinand Xu commented on HIVE-11912:
-------------------------------------
Thank you for the clarification.
The original purpose for HIVE-7858 is that ORC supports this way to configure
the table compression properties.
The patch LGTM. One minor question about the patch:
{noformat}
108 Map<String, String> defaultSerdeProps =
descriptor.getDefaultSerdeProps();
109 if (defaultSerdeProps != null) {
110 serdeProps.putAll(defaultSerdeProps);
111 }
{noformat}
Is that possible the original serde properties overrided by the default value?
