Chen Liang commented on HDFS-13880: ----------------------------------- [~shv] Masync is just the current name I picked for methods that do not need to go through the sync process (which is msync). Just replaced sync with async. Please feel free to propose a different term :). [~csun] thanks for the clarification. Will double check if {{HAServiceProtocol}} is currently synced by msync. > Add mechanism to allow certain RPC calls to bypass sync > ------------------------------------------------------- > > Key: HDFS-13880 > URL: https://issues.apache.org/jira/browse/HDFS-13880 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: namenode > Reporter: Chen Liang > Assignee: Chen Liang > Priority: Major > Attachments: HDFS-13880-HDFS-12943.001.patch, > HDFS-13880-HDFS-12943.002.patch > > > Currently, every single call to NameNode will be synced, in the sense that > NameNode will not process it until state id catches up.
