Danil Mironov commented on SPARK-2960:
--------------------------------------

The title of the issue is not that misleading, when one doesn't get 
spark-something running after 'spark-something' was typed in, it's commonly 
known as 'spark executables fail to start'. Following the symlinks does fix the 
issue in hand.

Having executables {quote}configured by {{SPARK_HOME}} and/or 
{{SPARK_CONF_DIR}} {quote} would be a nice solution, I'd vote for that.
This implies scripts treating those configurations as read-only and quitting 
early and loudly if the latter is missing or crippled. 
That's some rework though, not a bug to fix.

> The current scripts (e.g. pyspark) fail to run when they are executed via 
> symlinks. A common Linux scenario would be to have Spark installed somewhere 
> (e.g. /opt) and have a symlink to it in /usr/bin.
