Similar to this, I have a use case to compare Ansible Code with the Ambari Configs. The reason we are doing this is that we found several inconsistencies w.r.t to Ansible code and Ambari configs. But comparing both is a big task as there are many playbooks where we have Hadoop code so checking all the code base a heck. Any other option to do the comparison..... ... View more

I know this is a bit late to post but i have a web app that scans the table and gets results based on the rowkey provided in the call so it needs to support multi threading, here's a snip of the scan:     try(ResultScanner scanner = myTable.getScanner(scan)) { for (Result result : scanner) { //logic of result.getValue() and result.getRow() } }     i just saw https://hbase.apache.org/1.2/devapidocs/org/apache/hadoop/hbase/client/Result.html is one of those classes that is not thread-safe among others mentioned in this article. Is there an example of a fully thread-safe hbase app that scans results based on the rowkey provided or anything similar? I'm looking for an efficient and good example i can use for reference. I am now concerned that this piece of code might not yield proper results when i get simultaneous requests. ... View more

In Ambari, you click on the Hosts tab to see what services are installed on what host, but, you may need to go through them host by host. ... View more

One work around that I just tested - run the beeline with the following queue parameter: beeline -u "jdbc:hive2://local:10001/default;transportMode=http;httpPath=cliservice;principal=hive/_HOST@local.COM" -e "SELECT count(*) FROM log;" --hiveconf tez.queue.name=prd_am This will request the query to be executed in the prd_am queue. If the user has access to that queue allowed in Ranger, it will work fine. Still looking for a solution to use the default mapping defined in the YARN Capacity Scheduler configuration like: yarn.scheduler.capacity.queue-mappings=u:user1:dev_devs, g:devs:dev_devs ...
