Subject [jira] [Created] (AURORA-771) 'see log for details' in client output is confusing
Date Tue, 30 Sep 2014 00:59:33 GMT
Bill Farner created AURORA-771:
----------------------------------

             Summary: 'see log for details' in client output is confusing
                 Key: AURORA-771
                 URL: https://issues.apache.org/jira/browse/AURORA-771
             Project: Aurora
          Issue Type: Story
          Components: Client, Usability
            Reporter: Bill Farner
            Priority: Critical


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.
{noformat}
