参数:

config - configuration to use

返回:

a (distributed) blob store for high availability

抛出:

IOException - thrown if the (distributed) file storage cannot be created

createBlobServer

public static BlobServer createBlobServer(org.apache.flink.configuration.Configuration configuration,
                                          org.apache.flink.util.Reference<File> fallbackStorageDirectory,
                                          BlobStore blobStore)
                                   throws IOException

Creates the BlobServer from the given configuration, fallback storage directory and blob store.

参数:

configuration - for the BlobServer

fallbackStorageDirectory - fallback storage directory that is used if no other directory has been explicitly configured

blobStore - blob store to use for this blob server

返回:

new blob server instance

抛出:

IOException - if we could not create the blob storage directory

参数:

configuration - for the BlobCacheService

fallbackStorageDirectory - fallback storage directory

blobView - blob view

serverAddress - blob server address

返回:

new blob cache service instance

抛出:

IOException - if we could not create the blob storage directory
