I was checking the hadoop federation. Here the data nodes are common, only namespace will be different. How can we exclude some datanodes only from one namespace.

Dear Sandeep From this image i thought that deafult is tez and it also support llap& spark https://docs.hortonworks.com/HDPDocuments/HDP3/HDP-3.0.0/hive-overview/concepts/images/hive-sql-query-execution-process.png

I am using HDP-3.0. In previous versions hive.execution.engine was mapreduce/tez. Now in hdp3.0 that selection drop down is not there and default one is tez. some where i read that hive in hdp3.0 support tez(default),llap,spark. Is there any provision to directly set spark as the execution engine. Thanks & Regards Rahul

it comes at the time of mapreduce only right ?. if then it will be the map/reduce process. please grep the process id and take what exactly the process it is. If it is map/reduce process then one option is to recheck your mapreduce code. If that is also fine yarn cgroup may help. If you want to kill this process you need to kill the yarn job associated with it. To get the runnning yarn applications you can use RM UI or yarn application -list command To kill job : yarn application -kill application_id

In latest HDP 2.6.5 hbase version which maintains is hbase1.1.2. I agree that lot of bug fixes of future releases are added in this version. Some major improvements is not included in this version because i think lot of major class changes are there(eg: releted with indexing). The phoenix version which come with hdp is 4.7, the latest availble phoenix is phoenix4.14. Most new improvements and bug fixes of phoenix is not integrating to hdp's phoenix version. Thats why it has many bugs (mainly in hive,hbase,spark integrations). I can't manually test new phoenix with hdp's hbase because it's expecting hase1.1.9(some class are changed from hbase1.1.2). Can you please tell whether/when we can expect a updation in hbase/phoenix. Please treat this as priority. Thanks & Regards Rahul P
