Is there a good way to convert curl api json output to csv ? Actually when I do curl -X GET "http://lxhdpmasttst001.lowes.com:8088/ws/v1/cluster/scheduler" it gives output to json and I want to load it to hive or want to convert into csv so that everyone can read it easily.

@rajdip chaudhuri Can you please paste /var/log/hadoop/hdfs/<latest_NN>.log and /var/log/ambari-server/ambari-server.log files content. Also please check whether hdfs and ambari service is running.

When you upgrade your stack from 2.2 to 2.3 then you will have issue using hue or hive due to a bug. In hive config file you may have wrong value in templeton.libjars property = /usr/hdp/${hdp.version}/zookeeper,/usr/hdp/${hdp.version}/hive/lib/hive-common.jar/zookeeper.jar So change it to correct one. Actually this is a bug which occurs with upgrade from HDP 2.2 to 2.3. correct value is below /usr/hdp/${hdp.version}/zookeeper/zookeeper.jar,/usr/hdp/${hdp.version}/hive/lib/hive-common.jar

@Rahul Pathak I have ambari Version2.2.0.0 and hdp stack 2.3.4.0. I tried for other metrics for Resourcemanager but getting some weird error. Problem! Unable to compile query predicate: Invalid Query Token: token='(', previous token type=VALUE_OPERAND.

@Rahul Pathak @Neeraj Sabharwal : I am trying to configure grafan with ambari and trying to create graph but it is throwing me an error. So can you please point me to solution. Problem!

Hi Vinod, You can use following steps to apply patch on your server. 1. Download patch to local or server. 2. You can use below command to apply it under ambari home dir. $ patch -p0 -i /path/to/AMBARI-14466.patch

Divakar: Thanks for your consideration, but as I have mentioned above problem has been resolved by running build/env/bin/hue syncdb --noinput

Yes,you are right @artem Evits we should use views but for that we should have a dedicated server which would manage views,otherwise it may create overload on our ambari servers and we do some changes and restart ambari then users also may get impacted.
