Subject: Exporting column family data to csv

I want to export all the data of particular column family to the text file from Cassandra

I tried

copy keyspace.mycolumnfamily to '/root/ddd/xx.csv';

It gave me timeout error

I tried below in Cassandra.yaml

request_timeout_in_ms: 10000000
read_request_timeout_in_ms: 10000000
range_request_timeout_in_ms: 10000000
truncate_request_timeout_in_ms: 10000000

I still have no luck. Any advise how to achieve this? I am NOT limited to copy command.  What
is the best way to achieve this? Thanks in advance for the help.
