Colin Patrick McCabe created HDFS-3510: ------------------------------------------
Summary: Some FSEditLog pre-allocation problems in branch-1 Key: HDFS-3510 URL: https://issues.apache.org/jira/browse/HDFS-3510 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 1.0.0 Reporter: Colin Patrick McCabe Assignee: Colin Patrick McCabe Fix For: 1.0.0 In the FSEditLog, we want to avoid running out of space in the middle of writing an edit log operation to the disk. We do this by a process called "preallocation"-- reserving space on the disk for the upcoming edit log entries before beginning to write them. branch-1 has some major problems with the way it does preallocation. These problems can lead to corrupt edit logs when the disk runs out of space during an edit log sync operation. -- This message is automatically generated by JIRA.
