Hi Tim,
run-example is here:
https://github.com/ehiggs/spark/blob/terasort/bin/run-example
It should be in the repository that you cloned. So if you were at the
top level of the checkout, run-example would be run as ./bin/run-example.
Yours,

Hi all,
I'm trying to build the Spark-perf WIP code but there are some errors to
do with Hadoop APIs. I presume this is because there is some Hadoop
version set and it's referring to that. But I can't seem to find it.
The errors are as follows:

Hi all,
Quick one: when reading files, are the orders of partitions guaranteed
to be preserved? I am finding some weird behaviour where I run
sortByKeys() on an RDD (which has 16 byte keys) and write it to disk. If
I open a python shell and run the following:

local file system right? HDFS orders the file
based on names, but local file system often don't. I think that's why
the difference.
We might be able to do a sort and order the partitions when we create
a RDD to make this universal though.

ystem implementation that overrides the listStatus
method, and then in Hadoop Conf set the fs.file.impl to that.
Shouldn't be too hard. Would you be interested in working on it?

To add to Sean and Reynold's point:
Please correct me if I'm wrong, but Spark depends on hadoop-common which
also uses jetty in the HttpServer2 code. So even if you remove jetty
from Spark by making it an optional dependency, it will be pulled in by
Hadoop.
So you'll still see that your prog

Hi all,
A quick question about Tungsten. The announcement of the Tungsten
project is on the back of Hadoop Summit in Brussels where some of the
Flink devs were giving talks [1] on how Flink manages memory using byte
arrays and the like to avoid the overhead of all the Java types[2]. Is
there a
both Flink and Spark into one.This eases the
industry adaptation instead.
Thanking you.

great. I think the consensus from last time was that we would
put performance stuff into spark-perf, so it is easy to test different
Spark versions.
