Brian Hess commented on CASSANDRA-2527: ---------------------------------------- [~iamaleksey] - this ticket isn't only applicable to Hadoop, but to any analytics engine, including Spark. I think we should either reopen this ticket and retarget to Spark (though the same mechanism would be interesting to Hadoop, Flink, etc) or open a new one with the word "Spark" replacing the word "Hadoop", but otherwise the exact same idea. > Add ability to snapshot data as input to hadoop jobs > ---------------------------------------------------- > > Key: CASSANDRA-2527 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2527 > Project: Cassandra > Issue Type: New Feature > Reporter: Jeremy Hanna > Priority: Minor > Labels: hadoop > > It is desirable to have immutable inputs to hadoop jobs for the duration of > the job. That way re-execution of individual tasks do not alter the output. > One way to accomplish this would be to snapshot the data that is used as > input to a job. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
