@Victor The property "tez.tez-ui.history-url.base" is missing in your case. Please do the following to fix it. Tez --> Configs --> Advanced --> "Custom tez-site" --> "Add Property" Example: tez.tez-ui.history-url.base=http://ambariserver.exmaple.com:8080/#/main/view/TEZ/tez_cluster_instance Please make sure to replace the "http://ambariserver.exmaple.com:8080" with your own ambari server URL and then restart required services after saving this. . ...

@Victor In Older version of ambari (Like Ambari 2.4.2) the property value used to be slightly different like following Example: (for example only) tez.tez-ui.history-url.base=http://ambariserver.example.com:8080/#/main/views/TEZ/0.7.0.2.5.3.0-136/TEZ_CLUSTER_INSTANCE So please let us know your exact ambari version as well. ...

@Amit Ashish You can also use the "hadoop checknative" command on all the clusert hosts to find out if the snappy or other native libraries are installed properly on them or not? Example: # hadoop checknative 18/04/24 00:43:37 INFO bzip2.Bzip2Factory: Successfully loaded & initialized native-bzip2 library system-native 18/04/24 00:43:37 INFO zlib.ZlibFactory: Successfully loaded & initialized native-zlib library Native library checking: hadoop: true /usr/hdp/2.6.4.0-91/hadoop/lib/native/libhadoop.so.1.0.0 zlib: true /lib64/libz.so.1 snappy: true /usr/hdp/2.6.4.0-91/hadoop/lib/native/libsnappy.so.1 lz4: true revision:99 bzip2: true /lib64/libbz2.so.1 . ...

@Amit Ashish Which version of HDP are you using? Are you sure that all the host have the following packages installed? (it might be possible that when it is failing intermittently that time it might be executing the queries on the hosts which does not have these packages installed). Can you please install the following packages as mentioned in the DOC: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.3/bk_command-line-installation/content/install_compression_libraries.html Install Snappy on all the nodes in your cluster. At each node: For RHEL/CentOS/Oracle Linux: yum install snappy snappy-devel For SLES: zypper install snappy snappy-devel For Ubuntu/Debian: apt-get install libsnappy1 libsnappy-dev ... View more

@Robert Lepen At this point (based on the screenshot) you should be able to access the Terminal or web terminal to check the ambari server logs. Please try to open the URL in your browser : http://localhost:4200. (username: root, password: hadoop) Or try using the terminal to access the Sandbox: (port must be 2222) # ssh root@127.0.0.1 -p 2222 Enter Password: hadoop . Then check the log of ambari to see if there are any issues. Normally due to some resource issues it takes longer time to start. So better to kill some of the components like Zeppelin / Spark if you are not using them and put them in maintenance mode for next time. ... View more

@Manisha Pande In that case you cane add the "host_components/HostRoles/service_name" part in the same API call to also list the components on each host along with the Rack Info. Burt you will have to parse the output based on your requirement. Example: # curl -u admin:admin -H "X-Requested-By:ambari" -X GET http://hdfcluster1.example.com:8080/api/v1/clusters/TestCluster/hosts?fields=Hosts/rack_info,Hosts/host_name,host_components/HostRoles/service_name . ...

@Manisha Pande Can you please clarify what exactly do you mean by "check each service get host name and rack info"? In Each service where do you see the rack info? ... View more
