Rekha Joshi updated CASSANDRA-7269:
-----------------------------------
Attachment: CASSANDRA-7269.txt
> Make CqlInputFormat and CqlRecordReader consistent with comments
> ----------------------------------------------------------------
>
> Key: CASSANDRA-7269
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7269
> Project: Cassandra
> Issue Type: Bug
> Components: Hadoop
> Reporter: Jeremy Hanna
> Priority: Minor
> Labels: hadoop
> Attachments: CASSANDRA-7269.txt
>
>
> Both the CqlInputFormat and CqlPagingInputFormat have the following comment:
> {code}
> /**
> ...
> * the number of CQL rows per page
> * CQLConfigHelper.setInputCQLPageRowSize. The default page row size is
> 1000. You
> * should set it to "as big as possible, but no bigger." It set the LIMIT
> for the CQL
> * query, so you need set it big enough to minimize the network overhead,
> and also
> * not too big to avoid out of memory issue.
> ...
> **/
> {code}
> The property is used in both classes, but the default is only set to 1000 in
> CqlPagingRecordReader explicitly.
> We should either make the default part of the CqlConfigHelper so it's set in
> both places or update the comments in the CqlInputFormat to say that if it's
> not set, it will default to the java driver fetch size which is 5000.
