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.
> Add Progress Reporting to Cassandra OutputFormats

> Project: Cassandra
> Issue Type: Improvement
> Components: Hadoop, Tools

> Reporter: Samarth Gahire
> Assignee: Brandon Williams
> Priority: Minor
> Labels: bulkloader, hadoop, mapreduce, sstableloader
> Fix For: 1.1

> 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.
