Subject [jira] [Commented] (CASSANDRA-3859) Add Progress Reporting to Cassandra SstableLoader for BulkOutputFormat
Date Mon, 06 Feb 2012 19:17:59 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3859?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13201482#comment-13201482
] 

Brandon Williams commented on CASSANDRA-3859:
---------------------------------------------

Input formats would implement getProgress(), but I don't see an equivalent for output formats.
 CFOF isn't implementing any method like this and doesn't experience timeout problems, have
you actually experienced this?

> 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.
