Todd Lipcon updated HDFS-1497: ------------------------------ Attachment: hdfs-1497.txt Patch adds a check for sequential seqnos, and also a unit test that shows that we were failing to maintain this property before with empty hflushes. Running unit test suite now. > Write pipeline sequence numbers should be sequential with no skips or > duplicates > -------------------------------------------------------------------------------- > > Key: HDFS-1497 > URL: https://issues.apache.org/jira/browse/HDFS-1497 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs client > Affects Versions: 0.20-append, 0.22.0 > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Attachments: hdfs-1497.txt > > > In HDFS-895 we discovered that multiple hflush() calls in a row without > intervening writes could cause a skip in sequence number. This doesn't seem > to have any direct consequences, but we should maintain and assert the > invariant that sequence numbers have no gaps or duplicates. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
