[ https://issues.apache.org/jira/browse/SLIDER-664?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15065331#comment-15065331 ]

Here is some test
1)deploy tomcat servers in yarn containers
https://issues.apache.org/jira/browse/SLIDER-809
2) add the upload function into the tomcat.py script，upload war file to {tomcat-dir}/webapps
eg:
def uploadfile(self,env):
import params
#Don't need to re-call configure
env.set_params(params)
upload_cmd = format('hdfs dfs -copyToLocal {upload_app_file} {app_root}/apache-tomcat-7.0.62/webapps/')
os.system(upload_cmd)
copy_cmd = format('hdfs dfs -cp {upload_app_file} {tomcat_app_dir}/')
os.system(copy_cmd)
3) execute the custorm command ,eg:
slider operate demo-tomcat --cmd UPLOADFILE --containers container_1449127000251_0043_01_000002 --components TOMCAT -D site.global.hdfs_upload_file=/data/app.war
4) the app.war in hdfs are copied to {woriking-dir}/webapps
[root@xx webapps]# ls
app.war docs examples host-manager manager ROOT

> Key: SLIDER-664
> URL: https://issues.apache.org/jira/browse/SLIDER-664
> Project: Slider
> Issue Type: Improvement
> Components: agent, agent-provider, app-package
> Affects Versions: Slider 0.60
> Reporter: Sumit Mohanty
> Assignee: Sumit Mohanty
> Priority: Critical
>
> Slider application package allows defining of arbitrary commands. However, there is no way to execute these arbitrary commands using the Slider command line. A basic approach can be as follows:
> * App developer defines a custom command say "COMMAND" and a python function is mapped to this command in the same way as "START" or "INSTALL".
> * Using Slider-Agent the command can be issued against specific containers identified by the container id
> * While issuing commands, optional properties (name-value pairs) may be provided
> * Once command is issued a command id is returned that can be used to retrieve the command result
> * Command execution or the result is not persisted by Slider - so it is a best effort execution
