Hi Nishant,Yes, that works, I don't see the crash any more. I also don't use
the following sentence:SET
hive.input.format=org.apache.hadoop.hive.ql.index.compact.HiveCompactIndexInputFormat;
However, I don't see any benefit of indexing now. With or without indexing I
get the results back in same time!

Hi Sameer,
Try the following:
CREATE INDEX user_id_ordering_mode_index ON TABLE
products(user_id,ordering_mode) AS 'COMPACT' ROW FORMAT DELIMITED FIELDS
TERMINATED BY '\t' STORED AS TEXTFILE;
Let me know what it says.

Hi everyone,I have a TSV file (around 4 GB). I have creted a hive table on that
using the following command. It works finr without indexing. However, when I
create an index based on 2 columsn I get the following error:
