Cloudera HA HDFS NameNode не запускается

Question

Когда я пытаюсь включить High Availability для моей службы Cloudera HDFS, мой NameNode руководитель не запускается с этой ошибкой:

java.io.IOException: Cannot start an HA namenode with name dirs that need recovery. Dir: Storage Directory /disk0/dfs/nn state: NOT_FORMATTED

Это после того, как я уже бежать: hadoop namenode -format

Вывод hadoop namenode -format:

STARTUP_MSG: build = file:///var/lib/jenkins/workspace/generic-package-ubuntu64-12-04/CDH4.2.1-Packaging-Hadoop-2013-04-22_09-50-19/hadoop-2.0.0+960-1.cdh4.2.1.p0.9~precise/src/hadoop-common-project/hadoop-common -r 144bd548d481c2774fab2bec2ac2645d190f705b; compiled by 'jenkins' on Mon Apr 22 10:26:30 PDT 2013

кто-нибудь есть какие-нибудь идеи?

Answer 1

Если вы были начать ожидания NameNode вы можете попробовать:

hadoop namenod -bootstrapStandby 

... перед началом NameNode.
