Spark install fails intermittently

[ghost]

After launching/destroying a handful (~5) clusters, new launches fail with the error below. When I ssh into the driver node I notice that spark-2.3.0-bin-hadoop2.6.tgz is something like 300 bytes.

Do you want to terminate the 2 instances created by this operation?

[nchammas]

Starting with Spark 2.2.1, Spark is no longer hosted on S3. The project decided to move exclusively to the Apache mirror network. Try your launch with an earlier version of Spark, or install Flintrock from master.
