Jonathan Ellis commented on CASSANDRA-1124: ------------------------------------------- I briefly entertained the thought of improving Hadoop to make it mesh better with Cassandra instead of the other way around (in CASSANDRA-342) but it really does look very very difficult to get patches accepted over there. > Improve Cassandra to MapReduce locality sharing > ----------------------------------------------- > > Key: CASSANDRA-1124 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1124 > Project: Cassandra > Issue Type: Improvement > Components: Hadoop > Reporter: Jeremy Hanna > Priority: Minor > > Currently, the hadoop integration only passes the data's local node > information (ColumnFamilyRecordReader-RowIterator-getLocation). Hadoop can > take advantage of full locality and it's possible that we have full locality > configured in Cassandra. > So this improvement is for adding the full locality of the data into the > String in a way that hadoop can make use of it with its Job/Task Trackers. > This will allow for jobs to be potentially on the same rack and/or datacenter > if possible. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
