Todd Lipcon created HDFS-4618: --------------------------------- Summary: default for checkpoint txn interval is too low Key: HDFS-4618 URL: https://issues.apache.org/jira/browse/HDFS-4618 Project: Hadoop HDFS Issue Type: Bug Components: namenode Affects Versions: 2.0.4-alpha Reporter: Todd Lipcon Assignee: Todd Lipcon
The default checkpoint interval is currently set to 40k transactions. That's way too low (I don't know what idiot set it to that.. oh wait, it was me...) The old default in 1.0 is 64MB. Assuming an average of 100 bytes per txn, we should have the txn-count based interval default to at least 640,000. I'd like to change to 1M as a nice round number. -- This message is automatically generated by JIRA.
