I have seen that when you are working with ipv6, you can find this error. Because they use a split of ipv4,             String[] parts = address.getHostAddress().split("\\.");             String reverseIP = parts[3] + "." + parts[2] + "." + parts[1] + "."                       + parts[0] + ".in-addr.arpa"; I have found a posible solution. Put this in the hadoop-env.cmd, but i cant test yet. -Djava.net.preferIPv4Stack=true ... View more

If i insert a metric manually i can see the user in the drop-down of the grafana dashboard 0: jdbc:phoenix:sice1.tri.lan:2181> UPSERT into METRICS_METADATA_UUID(METRIC_NAME, APP_ID, INSTANCE_ID, UUID, UNITS, TYPE) VALUES ('regionserver.Users.hbase_metric_get_num_ops', 'hbase', '[B@570a62a5', '', '', ''); So i can say that the problem is in the ams-collector.

I 've got a problem when i want to see the Hbase-User Dashboard in grafana. I have changed the templates to see the Hbase Users, like i have seen in this document https://cwiki.apache.org/confluence/display/AMBARI/Enabling+HBase+Region%2C+User+and+Table+Metrics I`ve changed the templates in this 2 folders /var/lib/ambari-server/resources/common-services/HBASE/0.96.0.2.0/package/templates/ /var/lib/ambari-agent/cache/common-services/HBASE/0.96.0.2.0/package/templates/ But when i restart HBase service i can see the same lines in the "regenerated" file /etc/hbase/conf/hadoop-metrics2-hbase.properties I see all the times this 2 lines *.source.filter.class=org.apache.hadoop.metrics2.filter.RegexFilter hbase.*.source.filter.exclude=.*(Regions|Users|Tables).* Thanks ...

It is not an easy answer. I think that at the moment it is in incubator. When creating a table in hbase from version 1.1 of atlas you can see it in Apache Atlas. The problem that I have found is that if you feed that table with a csv file, you can not see the data lineage, as if you were working with Hive , It is not an easy answer.
