Built-in Job types
Azkaban allows custom job types to be added as plugins. However it also supplies several built-in job types. On top of the job parameters that can be set, each job type has additional properties that can be used.
Command
Command type of job can be set with type=command. It is a barebones command line executor. Many of the other job types wrap the command job type but constructs their own command lines.
| {.parameter}Parameter | {.description} Description | Required? | |
|---|---|---|---|
| command | The command line string to execute. i.e. ls -lh | yes | | |
| command. n | Where n is a sequence of integers (i.e 1,2,3...). Defines additional commands that run in sequential order after the initial command. | no | |
{.params}
Java Process
Java process jobs are a convenient wrapper for kicking off Java-based programs. It is equivalent to running a class with a main method from the command line. The following properties are available in javaprocess jobs:
| {.parameter}Parameter | {.description} Description | Required? | |
|---|---|---|---|
| java.class | The class that contains the main function. {code}i.e azkaban.example.text.HelloWorld{code} | yes | | |
| classpath | Comma delimited list of jars and directories to be added to the classpath. Default is all jars in the current working directory. | no | | |
| Xms | The initial memory pool start size. The default is 64M | no | | |
| Xmx | The initial maximum memory pool size. The default is 256M | no | | |
| main.args | A list of comma delimited arguments to pass to the java main function | no | | |
| jvm.args | JVM args. This entire string is passed intact as a VM argument. -Dmyprop=test -Dhello=world | no | |
{.params}
Noop
A job that takes no parameters and is essentially a null operation. Used for organizing your graph.
