When any namespace modification is performed by the > Active node, it durably logs a record of the modification to a majority of > these JNs. The Standby node is capable of reading the edits from the JNs, and > is constantly watching them for changes to the edit log. As the Standby Node > sees the edits, it applies them to its own namespace. In the event of a > failover, the Standby will ensure that it has read all of the edits from the > {color:#333333}*JounalNodes*{color} before promoting itself to the Active > state. This ensures that the namespace state is fully synchronized before a > failover occurs. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
