Todd Lipcon commented on HDFS-2123: ----------------------------------- hmm.. I added it as a deprecated key, but I think it's now going to have the wrong effect - ie it will treat the byte value as a number of transactions. Instead, it's probably better to emit a warning and ignore. Let me update the patch. > 1073: Checkpoint interval should be based on txn count, not size > ---------------------------------------------------------------- > > Key: HDFS-2123 > URL: https://issues.apache.org/jira/browse/HDFS-2123 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: name-node > Affects Versions: Edit log branch (HDFS-1073) > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Fix For: Edit log branch (HDFS-1073) > > Attachments: hdfs-2123.txt > > > Currently, the administrator can configure the secondary namenode to > checkpoint either every N seconds, or every N bytes worth of edit log.
