Can you share more details about your solution? Which config / system files you had to change?

I solved that issue by doing $ ambari-server upgrade. I am able to login to web ui now.

I checked ambari-server.log, it's saying database version issue.

I was trying to update ambari 2.2.0 to 2.2.1. I ran following commands on my machine: $ cd /etc/yum.repos.d/ $ wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.2.1.0/ambari.repo # Install $ yum install ambari-server $ ambari-server start First, time it was not giving any error when trying to start amari sever but was not able to login using "admin" "admin" username and password. Then i tried to stop and re-started Ambari and now i am getting below error. [root@ttsv-lab-vmdb-01 jdk64]# [root@ttsv-lab-vmdb-01 jdk64]# tail -f var/log/ambari-server/ambari-server.out^C [root@ttsv-lab-vmdb-01 jdk64]# ambari-server start Using python /usr/bin/python2 Starting ambari-server Ambari Server running with administrator privileges.

I am getting alert in Ambari for Host disk full: I checked my machine disk space, it's showing 100% full but i am not sure what should i delete as i have already deleted logs which were greater then 100MB size. But it's still showing same. Can anyone help me in this? I am using kafka, hbase and spark-streaming. Please find screenshot attached of my disk usage: screen-shot-2016-03-06-at-13742-pm.png screen-shot-2016-03-06-at-14231-pm.png Regards, ~Vinti

Hi, It was running fine, but suddenly, I started getting below error, Does anyone know what can be the issue? I restarted zookeepr from ambari as well.

Hi, I wanted to set "auto.offset.reset" to smallest in kafka consumer, as i my kafka consumer (spark-scala program) is not reading data from beginning currently. https://kafka.apache.org/08/configuration.html * smallest : automatically reset the offset to the smallest offset Thanks & Regards, Vinti

Initially i had two machines to setup hadoop, spark, hbase, kafka, zookeeper, MR2 . Each of those machines had 16GB of RAM. I used Apache Ambari to setup the two machines with the above mentioned services. Now i have upgraded the RAM of each of those machines to 128GB. How can i now tell Ambari to scale up all its services to make use of the additional memory? Do i need to understand how the memory is configured for each of these services? Is this part covered in Ambari documentation somewhere?

I could finally solve it by combining some of the steps mentioned above. I first checked what is the value of `zookeeper.znode.parent` in HBase. I tried setting that same value in Ambari, but that did not work because some of the metrics processes were already running on that machine. So, i had to `ps -ef | grep metrics` and kill all of them as they were caching the `/hbase` value. Watch the ambari metrics collector logs ( /var/log/ambari-metrics-collector/ambari-metrics-collector.log) while you do the below steps Steps: 0. tail -f /var/log/ambari-metrics-collector/ambari-metrics-collector.log 1. Stop Ambari 2. Kill all the metrics processes 3. curl --user admin:admin -i -H "X-Requested-By: ambari" -X DELETE http://`hostname -f`:8080/api/v1/clusters/CLUSTERNAME/services/AMBARI_METRICS => Make sure you replace CLUSTERNAME with your cluster name 4. Refresh Ambari UI 5. Add Service 6. Select Ambari Metrics 7. In the configuration screen, make sure to set the value of `zookeeper.znode.parent` to what is configured in the HBase service. By default in Ambari Metrics it is set to empty value. 8. Deploy
