setBeanClassLoader

public void setBeanClassLoader(java.lang.ClassLoader classLoader)

Specified by:

setBeanClassLoader in interface org.springframework.beans.factory.BeanClassLoaderAware

afterPropertiesSet

public void afterPropertiesSet()
                        throws java.lang.Exception

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Throws:

java.lang.Exception

setSecurityAuthMethod

public void setSecurityAuthMethod(SecurityAuthMethod securityAuthMethod)

Sets the security auth method.

Parameters:

securityAuthMethod - the new security auth method

setUserPrincipal

public void setUserPrincipal(java.lang.String userPrincipal)

Sets the user principal.

Parameters:

userPrincipal - the new user principal

setUserKeytab

public void setUserKeytab(java.lang.String userKeytab)

Sets the user keytab.

Parameters:

userKeytab - the new user keytab

setNamenodePrincipal

public void setNamenodePrincipal(java.lang.String namenodePrincipal)

Sets the used namenode principal.

Parameters:

namenodePrincipal - the namenode principal.

setRmManagerPrincipal

public void setRmManagerPrincipal(java.lang.String rmManagerPrincipal)

Sets the used resource manager principal.

Parameters:

rmManagerPrincipal - the resource manager principal

setFsUri

public void setFsUri(java.lang.String fsUri)

Sets the File System ('fs.defaultFS') URI.

Parameters:

fsUri - the file system uri

setRmAddress

public void setRmAddress(java.lang.String rmAddress)

Sets the Yarn ('yarn.resourcemanager.address') address.

Parameters:

rmAddress - the resource manager address

setSchedulerAddress

public void setSchedulerAddress(java.lang.String schedulerAddress)

Sets the Yarn ('yarn.resourcemanager.scheduler.address') address.

Parameters:

schedulerAddress - the resource manager scheduler address

setConfiguration

public void setConfiguration(org.apache.hadoop.yarn.conf.YarnConfiguration configuration)

Sets the parent configuration.

Parameters:

configuration - The configuration to set.

setResources

public void setResources(java.util.Set<org.springframework.core.io.Resource> resources)

Sets the configuration resources.

Parameters:

resources - The resources to set.

setProperties

public void setProperties(java.util.Properties properties)

Sets the configuration properties.

Parameters:

properties - The properties to set.

setInitialize

public void setInitialize(boolean initialize)

Indicates whether the configuration object should be initialized (true) or not. This option should normally be set to true (the default) as it causes the jars, streams and resources set to be loaded - postponing the initializing might cause these to become unreadable.

Parameters:

initialize - whether to initialize or not.

setRegisterUrlHandler

public void setRegisterUrlHandler(boolean register)

Indicates whether the configuration should register an URL handler (for allowing urls to understand HDFS prefixes, such as hdfs) or not. As this operation impacts an entire VM and can be invoked at most once per JVM, by default it is false.

Parameters:

register - whether to register an URL handler or not

createConfiguration

protected org.apache.hadoop.yarn.conf.YarnConfiguration createConfiguration(org.apache.hadoop.conf.Configuration existing)

Creates a configuration instance potentially using the existing one (passed as an argument - which can be null).

Parameters:

existing - the configuration

Returns:

configuration new or wrapped configuration
