Mohammad Kamrul Islam commented on OOZIE-578:
---------------------------------------------
Requirements:
The common use-cases are as follows:
* Use-case 1: User wants to run a shell/perl/python script.
* Use case 2: User wants to run a C++ executable.
* Use case 3: User wants to run a Java program.
* Use case 4: User wants to run script that contains a set of hadoop commands
which needs Kerberos.
* Use case 5: For all cases, user wants to pass the environment variable such
as LB_LIBRARY_PATH, JAVA_LIBRARY_PATH, PATH, CLASSPATH etc.
* Use case 6: User could write the control output to a file that could be
exposed to subsequent action through EL function.
Limitations:
* No interactive commands will be supported.
* Command can't be executed as different user such as sudo.
* User has to explicitly upload the required 3rd party packages (such as jar,
so lib, executable etc). Oozie will provide a way through Hadoop's Distributed
Cache.
* Since Oozie will execute the shell command into a Hadoop compute node, the
default installation of compute node might not be fixed. However, the most
common unix utilities are usually installed on all compute node.
Design Highlights:
* Oozie will execute the shell commands into a hadoop compute node.
* There will be a way of uploading the file through <file> and <archive> option.
* User can pass any environment variables through configuration
oozie.launcher.mapred.child.env .
* User can pass the requirements of extra resources (such as memory)
oozie.launcher.mapred.child.java_opts.
* Oozie should , by default, include the current directory into common
environment variables such as PATH, LD_LIBRARY_PATH, java_library_path,
CLASSPATH.

> Reporter: Mohammad Kamrul Islam
> Assignee: Mohammad Kamrul Islam
>
> Running a script (shell/perl/python/?) from a workflow is a very common
> use-case. Currently, Oozie user needs to write a custom java code to execute
> the script which is not convenient.
> This JIRA is to discuss the feasibility and scope of the feature. The
> proposed design of this feature will also be included.
