Hi, Azuryy Running the 'hdfs namenode -initializeSharedEdits' command on the active NN , I must to stop the Active NameNode.
I think when excuting the "./hdfs namenode -bootstrapStandby" command on Standby NameNode, the Active NameNode and JournalNameNodes should be alive, otherwise there is no HA. I was a beginner for QJM , there is something wrong, please correct me.
