What are the answers to this question since 2022? From what I'm seeing, links to repos of HDP 3.1.4 and earlier are behind a paywall aswell. Is there no free/opensource version of HDP/CDP anymore? And will never be?

@George-Megre The Master nodes firstly are not meant for launching tasks or interaction. Edge or gateway nodes are used to run client applications and cluster administration tools. Setup of Edge/gateway node is similar to any Hadoop node except no Hadoop cluster services runs on the GW/Edge nodes they are mere entry points and connection gateway to the Master Components like HDFS (NN) HBASE etc provide you have installed the client libraries. In your case, I am sure you have the Hbase client/gateway roles on the 3 nodes and not on the master noded. The HBase client role gives the connectivity to Hbase but again I don't see why you would like to connect /initiate the HBase shell from the master node? Geoffrey

@araujo do you have any suggestion for this case ?

Hi @Shelton, sorry for the delay in responding. I finally found the solution to my problem. I need to specify the column properties and then Compute Stats will work perfectly. ```sql ALTER TABLE myschema.mytable ADD COLUMNS (mycolumn1 TIMESTAMP NULL COMPRESSION DEFAULT_COMPRESSION, mycolumn2 TIMESTAMP NULL COMPRESSION DEFAULT_COMPRESSION); ```

Hi, even I am facing the same trouble when trying to load Ambari web page, it shows 502 error. It was working fine 2 days back but the error is showing from today when I tried to login in the morning. I have tried all the replies stated above, none worked. I will be grateful if someone can resolve this issue at the earliest. Many Thanks
