Eli Collins updated HDFS-2679: ------------------------------ Attachment: hdfs-2679.txt Pulled the common part out to HADOOP-7925 so it's explicit. > Add interface to query current state to HAServiceProtocol > ---------------------------------------------------------- > > Key: HDFS-2679 > URL: https://issues.apache.org/jira/browse/HDFS-2679 > Project: Hadoop HDFS > Issue Type: Sub-task > Affects Versions: HA branch (HDFS-1623) > Reporter: Eli Collins > Assignee: Eli Collins > Attachments: hdfs-2679.txt, hdfs-2679.txt, hdfs-2679.txt, > hdfs-2679.txt > > > Let's add an interface to HAServiceProtocol to query the current state of a > NameNode for use by the the CLI (HAAdmin) and Web UI (HDFS-2677). This > essentially makes the names "active" and "standby" from ACTIVE_STATE and > STANDBY_STATE public interfaces, which IMO seems reasonable. Unlike the other > APIs we should be able to use the interface even when HA is not enabled (as > by default a non-HA NN is active). -- This message is automatically generated by JIRA.
