metrics do not show
Hi! I build 2.6.1 ambari server and agent following docs. Then I succeed in installing zookeeper and ambari-metrics, and metrics in dashborad looks very good. But i find that metrics in AMBARI-METRICS and metrics in hosts can not show. I check the log but do not find error. Did i miss something import? Could someone help me? Thanks
Re: metrics do not show
Hi Xiang, If you have Grafana installed, can you check if the System-Servers and System-Home dashboard show data? -- Thanks and Regards, Aravindan Vijayan From: "xiang@sky-data.cn" Reply-To: "user@ambari.apache.org" Date: Friday, May 4, 2018 at 12:51 AM To: user Subject: metrics do not show But i find that metrics in AMBARI-METRICS and metrics in hosts can not show.
use krb-conf section to set udp_preference_limit = 1
Hi, According to https://community.hortonworks.com/content/supportkb/149955/errorcould-not-configure-server-because-sasl-confi.html, I need "udp_preference_limit = 1" for zookeeper to work with kerberos. How can I set this property using krb5-conf section in ambari blueprint? Thanks for any hint.
Re: use krb-conf section to set udp_preference_limit = 1
Hi, To allow end users setting ‘udp_preference_limit’ to 1 we implemented the following change: https://github.com/apache/ambari/pull/129 This will be available in 2.7.

Thanks. So the workaround for now is to use krb5.conf unmanaged by ambari?

does kerberos 1.15.1 need renew initial tickets to avoid GSSException?
Hi, I got GSSException when using hdfs command in my kerberonized HDP2.6 cluster. java.io.IOException: Failed on local exception: java.io.IOException: javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]; Host Details : local host is: " test-namenode.subnet1.hadoop.oraclevcn.com/10.0.1.68"; destination host is: "test-namenode.subnet1.hadoop.oraclevcn.com":8020; According to https://www.cloudera.com/documentation/enterprise/5-8-x/topics/cm_sg_sec_troubleshooting.html, it is because the initial tickets generated by kerberos >= 1.8.1 do not work for Oracle JDK 6 Update 26 and earlier. Is this still an issue for java1.8 used in my cluster? Do I still need "renewable = true" in my krb5.conf to generate renewable initial tickets and then manually renew them to work with java 1.8? Thanks for any hint.
