Hello,   I'm running into an issue related to a system that has two different versions of postgres installed. The system is running ambari 2.7.3.0 and my intention is for to run ambari server with postgres v10. However I recently noticed it was running with verision 9.2. I could tell b/c the postgres 9.2 service was active while the postgresql-10 service was inactive. Back when I upgraded the system to ambari 2.7.3.0 I confirmed it was up and running with postgres10 but after rebooting the machine I noticed it's now running with version 9.2. Is there an ambari configuration/setting that tells it which version of postgres to choose/run with?  ... View more

I have a customer filter that extends: org.apache.hadoop.hbase.filter.FilterBase I have overridden the: public boolean filterRowKey( byte [] data, int offset, int length) { ...} I have INFO level log statements in this method and I'm trying to find the log location where these logs would be written to when the map/reduce job is running/executed. Does anyone happen to know where these logs would appear. Typically I look at the job history server logs for the mapper/reducers (syslog), but I don't see my log entries there. I think that makes sense b/c they are logs written when the map(), reduce() methods are called. The logs I'm looking for are occurring before this point where it filters out records in the table. I'm trying to understand why my filter isn't working and was hoping to see some debug logs to help clarify what's going on. Any thoughts are appreciated! ... View more

I've upgraded to ambari to 2.7.3.0. In addition to upgrading ambari, I upgraded postgres from v9 to v10. After upgrading postgres, I can no longer start the ranger admin service within ambari. I've been seeing the notification: "Ranger admin service is not reachable, please restart the service." When I try to restart the service I observe the following log in /var/log/ranger/admin/catalina.out (see stack trace below):   Any ideas on what is going on here? I have a feeling there is a conflict between v9/v10 postgres db possibly, but I'm not entirely sure on this.   Dec 02, 2019 2:11:13 PM org.apache.catalina.core.StandardContext listenerStart SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'kmsKeyMgr': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: org.apache.ranger.biz.ServiceDBStore org.apache.ranger.biz.KmsKeyMgr.svcStore; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'serviceDBStore': Invocation of init method failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JPA EntityManager for transaction; nested exception is javax.persistence.PersistenceException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.2.v20131113-a7346c6): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: java.sql.SQLException: Connections could not be acquired from the underlying database!
