If the following command on the Ambari server host returns an
empty
items array then you must delete ZooKeeper (ZK) Failover
Controllers:
curl -u [AMBARI_USER]:[AMBARI_PW] -H "X-Requested-By: ambari"
-i
[AMBARI_PROTO]://localhost:[AMBARI_PORT]/api/v1/clusters/[CLUSTER_NAME]/host_components?HostRoles/component_name=ZKFC
-
On the Ambari Server host, issue the following DELETE commands:
curl -u [AMBARI_USER]:[AMBARI_PW] -H "X-Requested-By: ambari" -i -X
DELETE
[AMBARI_PROTO]://localhost:[AMBARI_PORT]/api/v1/clusters/[CLUSTER_NAME]/hosts/[NAMENODE_HOSTNAME]/host_components/ZKFC
curl -u [AMBARI_USER]:[AMBARI_PW] -H "X-Requested-By: ambari" -i -X DELETE
[AMBARI_PROTO]://localhost:[AMBARI_PORT]/api/v1/clusters/[CLUSTER_NAME]/hosts/[ADDITIONAL_NAMENODE_HOSTNAME]/host_components/ZKFC
-
Verify that the controllers are gone:
curl -u [AMBARI_USER]:[AMBARI_PW] -H "X-Requested-By: ambari" -i
[AMBARI_PROTO]://localhost:[AMBARI_PORT]/api/v1/clusters/[CLUSTER_NAME]/host_components?HostRoles/component_name=ZKFC
This command should return an empty items
array.
Modify HDFS configurations.
