---------------------------------
Summary: Agent error when trying to deploy Accumulo
Key: SLIDER-337
URL: https://issues.apache.org/jira/browse/SLIDER-337
Project: Slider
Issue Type: Bug
Components: agent-provider
Environment: Gentoo Linux, develop branch (035ebbd),
Hadoop-2.6.0-SNAPSHOT (r1619002)
Reporter: Josh Elser
Tried to start an Accumulo cluster:
{noformat}
slider create accumulo --image
hdfs://localhost:8020/slider/agent/slider-agent.tar.gz --template
/home/elserj/slider/app-packages/accumulo/target/apache-slider-accumulo-1.6.0-app-package-0.40/appConfig.json
--resources
/home/elserj/slider/app-packages/accumulo/target/apache-slider-accumulo-1.6.0-app-package-0.40/resources.json
{noformat}
SliderAM came up, but no Accumulo procs got started. Looking at the AM webapp,
the Accumulo master container kept cycling. Dug around in the NM/container logs
dir, and found the following stack:
{noformat}

I'm rusty on my Python, but I believe this means that in
{{slider-agent/src/main/python/resource_management/core/providers/__init__.py}}
{noformat}
if resource in provider[env.system.os_family]:
{noformat}
should be
{noformat}
if resource in provider.get(env.system.os_family):
{noformat}
to avoid the Exception when the key doesn't exist (alternatively try/except,
too), and get down to the {{default}} case.
