Nicholas Chammas commented on SPARK-5008:
-----------------------------------------
Though I'm not too familiar with this stuff yet, updating {{core-site.xml}} to cover all volumes
seems like the more future-proof way to go.
[~brdwrd] - Are you able to come up with a solution to the problem by updating {{core-site.xml}}?
We can just bake that into the default file that {{spark-ec2}} creates.
> Persistent HDFS does not recognize EBS Volumes
> ----------------------------------------------
>
> Key: SPARK-5008
> URL: https://issues.apache.org/jira/browse/SPARK-5008
> Project: Spark
> Issue Type: Bug
> Components: EC2
> Affects Versions: 1.2.0
> Environment: 8 Node Cluster Generated from 1.2.0 spark-ec2 script.
> -m c3.2xlarge -t c3.8xlarge --ebs-vol-size 300 --ebs-vol-type gp2 --ebs-vol-num 1
> Reporter: Brad Willard
>
> Cluster is built with correct size EBS volumes. It creates the volume at /dev/xvds and
it mounted to /vol0. However when you start persistent hdfs with start-all script, it starts
but it isn't correctly configured to use the EBS volume.
> I'm assuming some sym links or expected mounts are not correctly configured.
> This has worked flawlessly on all previous versions of spark.
> I have a stupid workaround by installing pssh and mucking with it by mounting it to /vol,
which worked, however it doesn't not work between restarts.
