public interface YarnEnvironmentConfigurer
Interface for YarnEnvironmentBuilder used from
a SpringYarnConfigurerAdapter.
Typically configuration is used as shown below.
@Configuration
@EnableYarn
static class Config extends SpringYarnConfigurerAdapter {
@Override
public void configure(YarnEnvironmentBuilder environment) throws Exception {
environment
.withClasspath()
.entry("cpEntry1")
.entry("cpEntry2")
.useDefaultYarnClasspath(true);
}
}
| Method Summary | |
|---|---|
YarnEnvironmentConfigurer |
entry(java.lang.String key,
java.lang.String value)
Specify an environment variable. |
YarnEnvironmentConfigurer |
includeLocalSystemEnv(boolean includeLocalSystemEnv)
Specify if existing system environment variables should be included automatically. |
YarnEnvironmentConfigurer |
propertiesLocation(java.lang.String... locations)
Specify properties locations. |
EnvironmentClasspathConfigurer |
withClasspath()
Specify a classpath environment variable. |
PropertiesConfigurer<YarnEnvironmentConfigurer> |
withProperties()
Specify properties with a PropertiesConfigurer. |
| Method Detail |

EnvironmentClasspathConfigurer withClasspath()
throws java.lang.Exception
Applies a new DefaultEnvironmentClasspathConfigurer into current
builder. Equivalents between JavaConfig and XML are shown below.
JavaConfig:
public void configure(YarnEnvironmentBuilder environment) throws Exception {
environment
.withClasspath()
.entry("cpEntry1")
.entry("cpEntry2")
.useDefaultYarnClasspath(true);
}
XML:
<yarn:environment>
<yarn:classpath use-default-yarn-classpath="true" delimiter=":">
cpEntry1
cpEntry2
</yarn:classpath>
</yarn:environment>
DefaultEnvironmentClasspathConfigurer for classpath
java.lang.Exception - if error occurred
YarnEnvironmentConfigurer entry(java.lang.String key,
java.lang.String value)
JavaConfig:
public void configure(YarnEnvironmentConfigure environment) throws Exception {
environment
.entry("myKey1","myValue1")
.entry("myKey2","myValue2");
}
XML:
<yarn:environment> myKey1=myValue1 myKey2=myValue2 </yarn:environment>
key - The environment keyvalue - The environment value
YarnEnvironmentConfigurer for chaining
YarnEnvironmentConfigurer propertiesLocation(java.lang.String... locations)
throws java.io.IOException
JavaConfig:
public void configure(YarnEnvironmentConfigure environment) throws Exception {
environment
.entry("myKey1","myValue1")
.entry("myKey2","myValue2")
.propertiesLocation("cfg-1.properties", "cfg-2.properties");
}
XML:
<yarn:environment properties-location="cfg-1.properties, cfg-2.properties"> myKey1=myValue1 myKey2=myValue2 </yarn:environment>
locations - The properties file locations
YarnEnvironmentConfigurer for chaining
java.io.IOException - if error occurredYarnEnvironmentConfigurer includeLocalSystemEnv(boolean includeLocalSystemEnv)
JavaConfig:
public void configure(YarnEnvironmentConfigure environment) throws Exception {
environment
.includeLocalSystemEnv(false);
}
XML:
<yarn:environment include-local-system-env="false"/>
includeLocalSystemEnv - if system env variables should be included
YarnEnvironmentConfigurer for chaining
PropertiesConfigurer<YarnEnvironmentConfigurer> withProperties()
throws java.lang.Exception
PropertiesConfigurer.
JavaConfig:
public void configure(YarnEnvironmentConfigure environment) throws Exception {
Properties props = new Properties();
environment
.withProperties()
.properties(props)
.property("myKey1", ",myValue1")
.and();
}
XML:
<util:properties id="props" location="props.properties"/>myValue1 </util:properties> <yarn:environment properties-ref="props"/>
PropertiesConfigurer for chaining
java.lang.Exception - if error occurred
