I am using ambari 2.2.1 and HDP 2.3.4 and ubuntu 12. I successfully completed the ambari setup through launch wizard but it never started the services. I am manually starting the services now through "start all" but it fails to start them. I get the following error for all the services : resource_management.core.exceptions.Fail: Execution of 'curl -sS -L -w '%{http_code}' -X GET 'http://xxxx:50070/webhdfs/v1/ats/done?op=GETFILESTATUS&user.name=hdfs'' returned status_code=503. I checked that the node is reachable from the server and hdfs is working fine. What am I missing here? Thanks ... View more
