What was the compression ratio you saw?
I get the correct results, but the data size is almost same as
searches = load '/user/testuser/aol_search_logs.txt' as (ID : int,
Query : chararray, QueryTime : chararray, ItemRank : int, ClickURL :
store searches into '/user/testuser/aol_search_logs.avro' using
I also tried -
SET avro.output.codec snappy
SET mapred.output.compress true
searches = load '/user/testuser/aol_search_logs.avro' using
store searches into '/user/testuser/aol_search_logs.snappy.avro' using
