tachyon not supported?

[ddsky]

I started instances successfully with the ./spark-ec2 script but at the end I don't get the information like http://master-hostname:8080 - I assume because I get No valid Tachyon version found; Tachyon won't be set up

I'm running this on windows, is this not supported?

Is this tachyon necessary, I see on AWS that the instances were started successfully. Is there another way I can get into the web ui?

For some reason the tachyon archive is missing at the url that the script uses.

I guess tachyon is not really necessary. I edited the "./spark_ec2.py" file, and applied these changes:

Old code:
modules = ['spark', 'ephemeral-hdfs', 'persistent-hdfs',
'mapreduce', 'spark-standalone', 'tachyon', 'rstudio']

New code:
modules = ['spark', 'ephemeral-hdfs', 'persistent-hdfs',
'mapreduce', 'spark-standalone']

After this I encountered no more errors, and I could connect to http://master-hostname:8080.

However, this spark-ec2 project seems to be pretty abandoned. You may be better off trying flintrock.
