Dear Jay what to say excellent answer , you are really one of the best here

mike_bronson7 · ‎02-03-2020

any way just for your information we get that curl -u admin:admin -H "X-Requested-By:ambari" -X GET "http://master_node:8080/api/v1/clusters/HDP/host_components?HostRoles/stale_configs=false&fields=HostRoles/service_name=HDFS" { "status" : 400, "message" : "Unable to compile query predicate: Invalid Query Token: token='=', previous token type=VALUE_OPERAND"

Dear Shelton , enjoy your vacation , and be careful from the corona -:)

I get A long list of all services , , any way not see there the HDFS but what we want is to verify only specific one service

mike_bronson7 · ‎02-03-2020

but I am asking diff , we want API that ask about specific service as HDFS or YARN , etc this post that you mentioned ( https://community.cloudera.com/t5/Support-Questions/how-to-know-if-any-service-in-ambari-cluster-nee... ) is about all services that required restart note - what we want is API that ask the specific service if required restart or not

mike_bronson7 · ‎02-03-2020

hi all how to verify if specific service required restart? for example - HDFS service in case HDFS service required restart then ambari will show this as is it possible by rest api to understand if service required restart or not? for example for - YARN / HIVE , etc

Dear Jay finally we found the issue it was about the mistake in /etc/hosts file instead of 127.0.0.1 , it was the ip address - 27.0.0.1 so we fix it and restart the postgresql and ambari now all are fine

mike_bronson7 · ‎01-30-2020

Jay can we use this to check in other way psql --host=master2 --port=8080 --username=ambari --password --dbname=bigdata Password for user ambari:ambari is this syntax is correct ? ?

mike_bronson7 · ‎01-30-2020

not clear to me how ambari server is up but port 8080 not open , I am also try to use other port as 8899 but the same behavior , very strange

mike_bronson7 · ‎01-30-2020

Jay is it possible to re-install ambari server? , without loosing data ?
