Subject RPC timeout error while exporting data from CQL
Date Wed, 18 Sep 2013 09:25:53 GMT
Hello all,

I am trying to export data from cassandra using CQL client. A column family
has about 100000 rows in it. when i am copying dta into csv file using COPY
TO command i get following rpc_time out error.

copy mycolfamily to '/root/mycolfamily.csv'
Request did not complete within rpc_timeout.

I am running in [cqlsh 3.1.6 | Cassandra 1.2.8 | *CQL spec 3.0.0* | Thrift
protocol 19.36.0]

how can i increase rpc timeout limit?

I tried adding rpc_timeout_in_ms: 20000 (defalut is 10000) in my
conf/cassandra.yaml file. but while restarting cassandra i get

[root@user ~]# null; Can't construct a java object for,2002:org.apache.cassandra.config.Config;
exception=Cannot create property=rpc_timeout_in_ms for
JavaBean=org.apache.cassandra.config.Config@71bfc4fc; Unable to find
property 'rpc_timeout_in_ms' on class: org.apache.cassandra.config.Config
Invalid yaml; unable to start server.  See log for stacktrace.

please help me.

Thanks in advance.
