## The purpose of the change To optimize the sharing mechanism of user jar, so that the jar of one job only needs to be downloaded once a machine. For more specific descriptions, please visit [FLINK-24293](https://issues.apache.org/jira/browse/FLINK-24293). ## Brief change log + Change getFileInternal method in AbstractBlobCache All tasks from the same job on a machine will download or read user jars concurrently. Those tasks may be executed by different TaskExecutors on this machine. We use FileLock instead of ReadWriteLock to control the process of downloading. + Change initLocalStorageDirectory method in BlobUtils Remove the random logic when building BLOB storage directory. -- This is an automated message from the Apache Git Service.
