In NonHA, If client tries to create the same file, which is already exists and open, then NameNode was throwing already being created exception immediately. For NonHA case, Retry policy was added to retry 5 times, each time after 60 sec(SOFT_LEASE_TIMEOUT).
However this retry was not working until HDFS-6478 fixed this. This led to behavior change and call will retry upto 5 min, before failing. Due to this downstream projects are facing issues. HBase reported it in HDFS-8270. Now the question is, Is retry of upto 5 mins for AlreadyBeingCreatedException is really necessary in NonHA case? Is 5 min waiting for a create operation failure is correct? Thanks Andreina J ________________________________ Andreina J 华为技术有限公司 Huawei Technologies Co., Ltd.
