Nicholas Chammas commented on SPARK-3213:
-----------------------------------------
Hey people, is the main motivation for using "Launch more like this" the fact
that spark-ec2 does not support directly adding slaves to an existing cluster
([SPARK-2008])?
> spark_ec2.py cannot find slave instances launched with "Launch More Like This"

> spark_ec2.py cannot find all slave instances. In particular:
> * I created a master & slave and configured them.
> * I created new slave instances from the original slave ("Launch More Like
> This").
> * I tried to relaunch the cluster, and it could only find the original slave.
> Old versions of the script worked. The latest working commit which edited
> that .py script is: a0bcbc159e89be868ccc96175dbf1439461557e1
> There may be a problem with this PR:
> [https://github.com/apache/spark/pull/1899].
