Thejas M Nair commented on HCATALOG-49:
---------------------------------------
Comments HCATALOG-49.patch
- AvroInputStorageDriver.getTypedObj and AvroOutputStorageDriver.getTypedObj
should be called recursively for map and list values. Complex type is supported
in the schema validation done in TypeConverter .
- AvroInputStorageDriver.convertToHCatRecord converts char field names to lower
case before looking up in avro schema, but TypeConverter.check doesn't. Does
avro Schema.getField do case sensitive comparison of field names ?
- AvroOutputStorageDriver.convertValue - it will bit more efficient to loop on
the position (for (int i=0; i < outputSchema., that way the column name does
not have to be looked up in outputSchema (ie HCatRecord.get(i) can be used
instead of HCatRecord.get(name, schema) )
- TestAvroInputStorageDriver - I think it will be useful to have some test
cases for the case where only some of the fields are requested, and the case
when some of the fields are partition keys.
(FYI, I am not a committer on HCatalog.)
