Review comment:
The resulting run script takes the following form if
`spark.executor.extraLibraryPath=path` is provided:
```
LD_LIBRARY_PATH=path:$LD_LIBRARY_PATH
org.apache.spark.executor.CoarseGrainedExecutorBackend
```
so there's no reason for quoting the actual executable. Thanks for pointing
out to unneeded interpolation.
