Hi Daniel,


You might need to run Hive Metatool to update the pointer to the new


hive --service metatool -listFSRoot <- shows the current pointer to NN

hive --service metatool -updateLocation <new-loc> <old-loc>  <- updates the
pointer to NN


I hope this helps.

Subject: Ambari 2.0 - Namenode Moved - ConnectionRefused Error


Hi all,


ich moved my Namenode to a new Node with Ambari 2.0. The moving itselve
worked fine but now I'm getting a ConnectionRefused-Error an HBase and Hive
(if i run a HiveQuery).


Error occurred executing hive query: Error while compiling statement:
FAILED: SemanticException MetaException(
Call From node0.test.local/ to node1.test.local:8020 failed on
connection exception: Connection refused; For
more details see:


Node1 is my old Namenode. Somewehre there is still node1 as Namnode listed.
But i cant find it. I searched all Config-xml-files there is no entry
regarding node1. Where is the mistake?
