Hi, I am planning to give exam on Tuesday.
I am currently having problem in compressing Avro/Parquet tables in Hive. I read on documentation that i have to set the following properties i.e.
SET parquet.compression = Snappy //for parquet
SET avro.output.codec = Snappy //for avro
Here is DDL:
CREATE TABLE avro_orders(order_id INT, order_Date bigint, order_customer_id INT, order_Status String) STORED AS AVRO;
I have also added to --auxpath
However i am still not able to achieve compression with the use of these properties. Can anyone give me a clue abut what i am doing wrong ?
I am facing similar problem with sqoop. I can't compress Avro/Parquet files however i can compress text files.
Thanks in advance
