Subject [jira] [Commented] (SPARK-5008) Persistent HDFS does not recognize EBS Volumes
Date Sun, 11 Jan 2015 18:03:34 GMT


Brad Willard commented on SPARK-5008:

[~nchammas] I can try that once I get back into the office. Probably by Wednesday. Once I
update the core-site.xml, what's the correct way to sync it to all the slaves?

> 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.
