Hello Community, I have a daily ingestion of data in to HDFS . From data into HDFS I generate Hive external tables partitioned by date . My qestion is as follows , should I run MSCK REPAIR TABLE tablename after each data ingestion , in this case I have to run the command each day. Or running it just one time at the table creation is enough . Thanks a lot for your answers Best regards

@ Jay Kumar SenSharma Hello , Currently, I have a 3 nodes cluster with one node including both ambari server and ambari agent and the other 2 nodes just include ambari agent. Do you think that this is a proper choice, is it better to have a node only dedicated to ambari server ( without any ambari agent , or master /slave services ) ? the etc/hosts file is the same for the 3 nodes of the cluster and I am aware of the fact the port 8441 in not working properly for the ambari agents but I don't know how to fix this issue Any suggestions about opening the port 8441 properly in the nodes ( I guess this port shall be opened for the 3 nodes of the cluster since I have ambari agents in the 3 nodes ) Thanks a lot in advanc efor your feedback

masterambariserver.pngHello, I need some clarifications about the way to install a hadoop cluster with Ambari , I tried several methods but unfortunately, none of them has worked properly ( I usually end up with a failing start of all the services such as namenode HDFS spark server etc, and heartbeats lost for all the nodes of the cluster) . let's make the hypothesis that I want to install a 3 nodes cluster Usually I install an ambari server in one node , and ambari agents in the 3 nodes , so the node where the ambari server is set will also include an ambari agent as well as master/slave services from the HDP Stack such as namenode datanode , spark server etc, with this method , the established cluster is totally failing since all services can't even start and heartbeats from all the ambari agents are lost. My questions are as follows : Do you have any explanations about the services start/heartbeats fail I got for the method described above ? Shall I install the ambari server in one node , this node will be totally dedicated to the ambari server , so for this node, we won't have any ambari agents or HDP services, in the hosts confirmation step of the ambari wizard install , I intend to not mention this node but I will include it is private SSH key in the table below the registration of hosts,ambariagentslavenode.png the repartition of the master /slave services will not take this node into consideration either . Do you think that with this method I will get better results? I included the ambari agents /ambari server log files for my current installation Thanks a lot in advance for your feedbacks

Hello , I managed to set a 3 nodes cluster using the local repositories for ambari 2.4.2 and HPP 2.5. The installation of the different services succeeded during the step 9 of the ambari wizard install , but almost all the services failed to start. Once connected to the cluster dashboard via the ambari web UI in the port 8080 , I got 31 alerts with the heartbeats lost for all the services, the master processes ( such as name node secondary namenode , hive server etc) failing to start. I also got a failure message from the namenode faling to connect to the master node in the port 8020. Finally the start/stop options of the different services are disabled via the ambari web UI ( see enclosed scree shots) I already stopped the different ambari agents and ambari server and restarted them but this doesn't resolve the issues I also tried to start the namenode from the CLI and It didn't work either . Any help with this please Best regards
