BlobLibraryCacheManager

public BlobLibraryCacheManager(PermanentBlobService blobService,
                               BlobLibraryCacheManager.ClassLoaderFactory classLoaderFactory)

方法详细资料

registerClassLoaderLease

public LibraryCacheManager.ClassLoaderLease registerClassLoaderLease(org.apache.flink.api.common.JobID jobId)

从接口复制的说明: LibraryCacheManager

Registers a new class loader lease for the given jobId. The user code class loader for this job will be valid as long as there exists a valid lease for this job.

指定者:

registerClassLoaderLease 在接口中 LibraryCacheManager

参数:

jobId - jobId for which to register a new class loader lease

返回:

a new class loader lease for the given job

shutdown

public void shutdown()

从接口复制的说明: LibraryCacheManager

Shuts the library cache manager down. Thereby it will close all open LibraryCacheManager.ClassLoaderLease and release all registered user code class loaders.

指定者:

shutdown 在接口中 LibraryCacheManager
