HDFS 20 append: Disallow pipeline recovery if a file is already being lease recovered -------------------------------------------------------------------------------------
Key: HDFS-1555 URL: https://issues.apache.org/jira/browse/HDFS-1555 Project: Hadoop HDFS Issue Type: Improvement Affects Versions: 0.20-append Reporter: Hairong Kuang Assignee: Hairong Kuang Fix For: 0.20-append When a file is under lease recovery and the writer is still alive, the write pipeline will be killed and then the writer will start a pipeline recovery. Sometimes the pipeline recovery may race before the lease recovery and as a result fail the lease recovery. This is very bad if we want to support the strong recoverLease semantics in HDFS-1554. So it would be nice if we could disallow a file's pipeline recovery while its lease recovery is in progress. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
