Name of an existing table to use for the test. Alternatively, the tool can create the new table using the same table and partition schema as the source table. Specifies whether output should be colorized. This is useful when running multiple times against already existing table: for every next run, set this flag to (num_threads * num_rows_per_thread * column_num + seq_start). The configured value must match the Hive hive.metastore.uris configuration.

'[1, "foo", 2, "bar"]'. If left empty, the test automatically creates a table of pre-defined columnar structure with unique name and uses it to insert auto-generated data. For maximum speed I would suggest to 1) issue hadoop fs -rm -r -skipTrash table_dir/* first to remove old data fast without putting files into trash because INSERT OVERWRITE will put all files into Trash and for very big table this will take a lot of time.
