Order of local operations and waiting for downstream DNs now reflects the pre HDFS-265 logic. > Fix hsync and hflush semantics. > ------------------------------- > > Key: HDFS-3979 > URL: https://issues.apache.org/jira/browse/HDFS-3979 > Project: Hadoop HDFS > Issue Type: Bug > Components: data-node, hdfs client > Affects Versions: 0.22.0, 0.23.0, 2.0.0-alpha > Reporter: Lars Hofhansl > Assignee: Lars Hofhansl > Attachments: hdfs-3979-sketch.txt, hdfs-3979-v2.txt > > > See discussion in HDFS-744. The actual sync/flush operation in BlockReceiver > is not on a synchronous path from the DFSClient, hence it is possible that a > DN loses data that it has already acknowledged as persisted to a client. > Edit: Spelling. -- This message is automatically generated by JIRA.
