@SchmidtS If In case you are not currently using the latest version of the Impala ODBC driver, please update the driver to the latest version (2.6.16 currently). Please note that 2.6.16 supports CDH6 so there should not be any incompatibility.
You can download the latest version of Impala ODBC driver in the below link:

The following areas normally cause this problem: 1) the connection from Ambari agent host to Ambari Server got lost. 2) firewall issue blocked connections. 3) hostname and IP address are not being set correctly in /etc/hosts You can compare the output using these APIs: > curl u user:paswd http://AmbariHost:8080/api/v1/hosts

@vinod_artga To resolve this issue, open /opt/cloudera/cm/bin/gen_credentials.sh for editing and add the following to the very end of the script: exit ${PIPESTATUS[0]} And then try generating Kerberos credentials once more. If it fails again, you should see much more detail assisting in troubleshooting. This will be addressed in a future release of Cloudera Manager.

I was having this error and Iliterally spent days scouring the Web for an answer. It turned out in my case that the order matters. The correct order was: olcTLSCACertificateFile, olcTLSCertificateKeyFile, olcTLSCertificateFile.

To get the number of vcores and memory used for a particular queue in the cluster
You can get this information in the cluster utilization report, please go through the below doc for more information:
https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/admin_cluster_util_report.html
Also, if you want to see the resources used for each application, please go through the below KB article:
https://my.cloudera.com/knowledge/How-to-calculate-memory-and-v-core-utilization-for-each-of-the?id=271149 another option is Using yarn application -status command, you can get the Aggregate Resource Allocation for an application. For e.g. yarn application -status application_ID (for one of completed applications), one of the rows returned is: Aggregate Resource Allocation : 46641 MB-seconds, 37 vcore-seconds This gives an aggregate memory and CPU allocations in seconds. https://my.cloudera.com/knowledge/How-to-calculate-memory-and-v-core-utilization-for-each-of-the?id=271149

To resolve the issue, import the Ambari certificates to the Ambari truststore. To import the Ambari certificates, do the following:
STEP 1:
Get certificate from ambari-server
echo | openssl s_client -showcerts -connect <AMBARI_HOst>:<AMBARI_HTTPs_PORT> 2>&1 | sed --quiet '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/ambari_certificate.cr
STEP 2:
Get path of ambari trustore and truststore password from Ambari properties
cat /etc/ambari-server/conf/ambari.properties |grep truststore
As per your ambari.properties below is the path and password :-
ssl.trustStore.password=refer from ambari.property file
ssl.trustStore.path=/etc/ambari-server/conf/ambari-server-truststore
STEP 3:
keytool -importcert -file /tmp/ambari_certificate.crt -keystore <keystore-path>
