                        InetSocketAddress serverAddress)
                 throws IOException

抛出:

IOException

BlobCacheService

public BlobCacheService(org.apache.flink.configuration.Configuration blobClientConfig,
                        org.apache.flink.util.Reference<File> storageDir,
                        BlobView blobView,
