Agree. In fact, we need to also document how Slider scripts can be debugged
during development.
If you do not mind can you open a JIRA at
https://issues.apache.org/jira/browse/SLIDER describing the requirements
of
debugging during development time and post development. I will use that
JIRA to drive the issue.

Thanks Sumit,
The only concern about script language is you don't know the compile
error
until runtime. And in fact it's not arbitrary script it depends on the
library in slider for example
/python/resource_management/core/resources/system.py

Actually, you can debug it after deploying it once. This will require
setting some YARN variables to ensure containers are not released even
if
the application fails. The agent logs report back the commands being
invoked and the parameters used to invoke them. Let me try to write
that
up
on the wiki. *I will need a day or so.*
The choice of python was mostly a reflection of going for scripting
language that works on Windows and linux. As such it is possible to use
any
scripting language as long as the agent code is modified to handle
various
script types. Of course, today the only supported/tested one is python.

May I ask why do you choose python to write the command script. And
is
there any other language? I find difficult to debug because each
time
if I
find an issue I have to change file package upload to hdfs, rerun and
I'm
not very familiar with python
