Jing Zhao created HDFS-5076: ------------------------------- Summary: Create http servlets to enable querying NN's last applied transaction ID and most recent checkpoint's transaction ID Key: HDFS-5076 URL: https://issues.apache.org/jira/browse/HDFS-5076 Project: Hadoop HDFS Issue Type: New Feature Affects Versions: 3.0.0 Reporter: Jing Zhao Assignee: Jing Zhao Priority: Minor
Currently NameNode already provides RPC calls to get its last applied transaction ID and most recent checkpoint's transaction ID. It can be helpful to provide servlets to enable querying these information through http, so that administrators and applications like Ambari can easily decide if a forced checkpoint by calling saveNamespace is necessary. -- This message is automatically generated by JIRA.
