ZanderXu created HDFS-17385: ------------------------------- Summary: [FGL] Replace the global FS locking with directory tree-based fine-grained locking Key: HDFS-17385 URL: https://issues.apache.org/jira/browse/HDFS-17385 Project: Hadoop HDFS Issue Type: Improvement Reporter: ZanderXu
Second, we can replace the global FS locking with directory tree-based fine-grained locking. This ticket doesn't remove this global FS locking, it just replaces the global FS write lock with the global FS read lock and directory tree-based fine-grained lock. For block-related operations and DN-related operations still need the global BM lock. The lock order should be: * The global FS lock * The global BM lock * The directory tree-based fine-grained lock This ticket should supports: * End-user can choose lock mode ** One global lock mode ** Global FS lock and global BM lock mode ** Global FS read lock, global BM lock and tree-based fine-grained lock -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
