@Robert Jonczy To fix the issue, could you please try running hbck tool with -repair option

@uri ben-ari Please try the curl command with double quotes (escaping the double quotes needed as part of curl rrequest) curl -H "X-Requested-By: ambari" -u admin:admin -X PUT -d "{\"RequestInfo\":{\"query\":\"ServiceComponentInfo/component_name.in(${LIST})\"},\"ServiceComponentInfo\":{\"recovery_enabled\":\"true\"}}" http://localhost:8080/api/v1/clusters/HDP01/components?

@Anand Pawar Please take a look at this FAQ list here https://hortonworks.com/services/training/certification/hdp-certified-developer-faq-page/ On that list, please take a look at 'What are the minimum requirements of my computer?'. Although going through all of them will be helpful.

What do you mean by there is nothing in namenode and secondarynamenode folder? Did you try recovering it using the steps described in the HA link ?

rchoksi · ‎04-02-2017

@Simran Kaur Looking at this error, could you please verify if HA is actually enabled for Namenode. Please go through the steps here http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.18/bk_ambari-user-guide/content/_namenode_high_availability.html

@Sriram Hadoop There doesn't seem to be an easy way to find the owner of ephemeral nodes in Zookeeper. You could still take a look at this link, it seems useful. http://zookeeper-user.578899.n2.nabble.com/Identify-ephemeral-node-owner-td6221016.html I also an open issue related to this, but no progress on it for years. https://issues.apache.org/jira/browse/ZOOKEEPER-1587 https://issues.apache.org/jira/browse/ZOOKEEPER-829
