Andrew Wang commented on HDFS-12603: ------------------------------------ Thanks Xiao, I've reverted from trunk and branch-3.0 too. It'd be great if you dig into it a little more. I'd still be okay with a sleep in the end, if it comes to that, but I've had luck in the past by holding a lock that pauses everything after initialization, doing the mocking, then releasing the lock. > Enable async edit logging by default > ------------------------------------ > > Key: HDFS-12603 > URL: https://issues.apache.org/jira/browse/HDFS-12603 > Project: Hadoop HDFS > Issue Type: Improvement > Components: namenode > Affects Versions: 2.8.0, 2.9.0, 3.0.0-alpha1 > Reporter: Andrew Wang > Assignee: Andrew Wang > Attachments: HDFS-12603.001.patch, HDFS-12603.002.patch, > HDFS-12603.003.patch, HDFS-12603.branch-2.01.patch, > HDFS-12603.branch-2.02.patch > > > HDFS-7964 added support for async edit logging.
