Subject: [jira] [Updated] (CASSANDRA-3859) Add Progress Reporting to
 Cassandra OutputFormats

Brandon Williams updated CASSANDRA-3859:
----------------------------------------

    Attachment: 0001-add-progress-reporting-to-BOF.txt

ProgressableOutputHandler was supposed to handle that case, but it looks like it doesn't actually produce enough output to avoid the timeout, so instead this updated patch polls the future and reports the progress every couple of seconds until it completes.

> 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.
