Pre-allocate HDFS edit log files after writing version number -------------------------------------------------------------
Key: HDFS-2759 URL: https://issues.apache.org/jira/browse/HDFS-2759 Project: Hadoop HDFS Issue Type: Sub-task Components: name-node Affects Versions: HA branch (HDFS-1623) Reporter: Aaron T. Myers Assignee: Aaron T. Myers In HDFS-2709 it was discovered that there's a potential race wherein edits log files are pre-allocated before the version number is written into the header of the file. This can cause the standby to read an invalid version. We should write the header, then pre-allocate the rest of the file after this point. -- This message is automatically generated by JIRA.
