                                                            scala.Function1<String,scala.collection.Seq<T>> extract)

parseAllocatedFromJsonFile

public static scala.collection.Seq<org.apache.spark.resource.ResourceAllocation> parseAllocatedFromJsonFile(String resourcesFile)

parseAllocated

public static scala.collection.Seq<org.apache.spark.resource.ResourceAllocation> parseAllocated(scala.Option<String> resourcesFileOpt,
                                                                                                String componentName)

getOrDiscoverAllResources

public static scala.collection.immutable.Map<String,ResourceInformation> getOrDiscoverAllResources(SparkConf sparkConf,
                                                                                                   String componentName,

Gets all allocated resource information for the input component from input resources file and the application level Spark configs. It first looks to see if resource were explicitly specified in the resources file (this would include specified address assignments and it only specified in certain cluster managers) and then it looks at the Spark configs to get any others not specified in the file. The resources not explicitly set in the file require a discovery script for it to run to get the addresses of the resource. It also verifies the resource allocation meets required amount for each resource.

Parameters:

sparkConf - (undocumented)

componentName - (undocumented)

resourcesFileOpt - (undocumented)

Returns:

a map from resource name to resource info

getOrDiscoverAllResourcesForResourceProfile

public static scala.collection.immutable.Map<String,ResourceInformation> getOrDiscoverAllResourcesForResourceProfile(scala.Option<String> resourcesFileOpt,
                                                                                                                     String componentName,
                                                                                                                     ResourceProfile resourceProfile,
                                                                                                                     SparkConf sparkConf)

This function is similar to getOrDiscoverallResources, except for it uses the ResourceProfile information instead of the application level configs.

It first looks to see if resource were explicitly specified in the resources file (this would include specified address assignments and it only specified in certain cluster managers) and then it looks at the ResourceProfile to get any others not specified in the file. The resources not explicitly set in the file require a discovery script for it to run to get the addresses of the resource. It also verifies the resource allocation meets required amount for each resource.

Parameters:

resourcesFileOpt - (undocumented)

componentName - (undocumented)

resourceProfile - (undocumented)

sparkConf - (undocumented)

Returns:

a map from resource name to resource info
