Subject [jira] [Commented] (CASSANDRA-3859) Add Progress Reporting to Cassandra OutputFormats
Date Wed, 22 Feb 2012 07:53:06 GMT


Chris Goffinet commented on CASSANDRA-3859:

Brandon, one thing I could think of, is if they are adding a lot of batches, we don't actually
call progress until the loop is over.

> When we are using the BulkOutputFormat to load the data to cassandra. We should use the
progress reporting to Hadoop Job within Sstable loader because while loading the data for
particular task if streaming is taking more time and progress is not reported to Job it may
kill the task with timeout exception.
