Subject Re: SparkSpark-perf terasort WIP branch
Date Wed, 11 Mar 2015 04:16:28 GMT
Hi Ewan,

Sorry it took a while for us to reply. I don't know spark-perf that well,
but I think this would be problematic if it works with only a specific
version of Hadoop. Maybe we can take a different approach -- just have a
bunch of tasks using the HDFS client API to read data, and not relying on
input formats?
