Cassandra CQLSH OperationTimedOut error=Client request timeout. See Session.execute[_async](timeout)
<p>I want to transfer data from one Cassandra cluster (reached via 192.168.0.200) to another Cassandra cluster (reached via 127.0.0.1). The data is 523 rows but each row is about 1 MB. I am using the COPY FROM and COPY TO command. I get the following error when I issue the COPY TO command:</p>

<pre><code>Error for (8948428671687021382, 9075041744804640605):
OperationTimedOut - errors={
'192.168.0.200': 'Client request timeout. See Session.execute[_async](timeout)'},
last_host=192.168.0.200 (will try again later attempt 1 of 5).
</code></pre>

<p>I tried to change the <code>~/.cassandra/cqlshrc</code> file to:</p>

<pre><code>[connection]
client_timeout = 5000
</code></pre>

<p>But this hasn't helped.</p>
