Bill Farner updated AURORA-771:
-------------------------------
    Description: 
This approach is taken in several places in response to a non-successful RPC:
{noformat}
$ grep -R ' see log for details' src/main/python/
src/main/python/apache/aurora/client/cli/cron.py:        err_msg=("Error 
scheduling job %s; see log for details" % context.options.jobspec))
src/main/python/apache/aurora/client/cli/cron.py:        err_msg=("Error 
descheduling job %s; see log for details" % context.options.jobspec))
src/main/python/apache/aurora/client/cli/cron.py:        err_msg=("Error 
starting cron job %s; see log for details" % context.options.jobspec))
src/main/python/apache/aurora/client/cli/cron.py:        err_msg=("Error 
getting cron status for %s; see log for details" % jobkey))
src/main/python/apache/aurora/client/cli/jobs.py:      raise 
context.CommandError(EXIT_COMMAND_FAILURE, "Error reported by scheduler; see 
log for details")
src/main/python/apache/aurora/client/cli/jobs.py:          err_msg="Error 
loading configuration; see log for details")
src/main/python/apache/aurora/client/cli/jobs.py:        
context.print_err("Kill of shards %s failed with error; see log for details" % 
batch)
src/main/python/apache/aurora/client/cli/jobs.py:      context.print_err("Error 
restarting job %s; see log for details" % str(job))
src/main/python/apache/aurora/client/cli/jobs.py:          "Server could not 
find running job to update: see log for details")
src/main/python/apache/aurora/client/cli/jobs.py:        err_msg="Server could 
not populate job config for comparison; see log for details.")
src/main/python/apache/aurora/client/cli/jobs.py:        err_msg="Update 
failed; see log for details.")
src/main/python/apache/aurora/client/cli/update.py:        err_msg="Failed to 
start scheduler-driven update; see log for details.")
src/main/python/apache/aurora/client/cli/update.py:      err_msg="Failed to 
pause scheduler-driven update; see log for details")
src/main/python/apache/aurora/client/cli/update.py:      err_msg="Failed to 
resume scheduler-driven update; see log for details")
src/main/python/apache/aurora/client/cli/update.py:      err_msg="Failed to 
abort scheduler-driven update; see log for details")
{noformat}

Take this command and output for example:
{noformat}
$ aurora2 beta-update start devcluster/www-data/devel/hello_world 
/vagrant/hello_world.aurora
log(info): Starting update for: hello_world
log(info): Starting new HTTP connection (1): 192.168.33.7
log(info): Starting new HTTP connection (1): 192.168.33.7
log(info): Message from scheduler: Job is unchanged by proposed update.
Error: Failed to start scheduler-driven update; see log for details.
log(info): Error executing command: Failed to start scheduler-driven update; 
see log for details.
Error executing command: Failed to start scheduler-driven update; see log for 
details.
{noformat}

In this case, the line containing "see log for details" makes me think that i'm 
expected to look at a log file somewhere, not that i should read the line 
immediately preceding.  It would be great if this output looked more like:

{noformat}
$ aurora2 beta-update start devcluster/www-data/devel/hello_world 
/vagrant/hello_world.aurora
Invalid request: Job is unchanged by proposed update.
