I figured this one out - the hive-jdbc.jar driver that comes with HDP 2.6.1 is not compatible with the Spark2 Thrift Server. It's also not compatible with the Hive 1.2 that ships with 2.6.1. If you just grab an older version of the driver, it works as expected, using the connection settings described above. Port 10016 for Spark2, port 10015 for the original...

Queries run through LLAP don't appear in the Yarn application manager GUI, nor do they appear in the Tez view - How can I check the status of a query running in LLAP - like % done, etc?

So far, I've figured out that a connection string like this is what you need: jdbc:hive2://<thrift server>:10016/<dbname> And the driver class is just like Hive: org.apache.hive.jdbc.HiveDriver However, the hive-jdbc.jar file is supposed to work, but doesn't. I get this error: Required field 'client_protocol' is unset! Struct:TOpenSessionReq(client_protocol:null, configuration:{use:database=default})

I want to connect Aqua Data Studio to the Spark2 Thrift Server on our cluster. Can someone point me in the right direction as far as connection string and drivers, etc?

Thanks. I'll give it a try.

I'm trying to install Slider on HDP 2.6.1 so I can enable LLAP. During the install process, it wants to know which of my servers should have the client software. Do I need the client software on all the data nodes in order to leverage the whole cluster? Or is the client software just for performing CLI commands, etc? Similar question for Druid. Thanks!

Is there a way to do this on a per-server basis? I have some edge nodes where restarting services doesn't seem to work and I get this error....

One note: The example linked lists "tag":"version14534007568115" in the JSON sent to Ambari. Through trial-and-error, it looks like this must include a valid timestamp AFTER the most recent change to the queue configs, otherwise the command fails with a huge stack trace that isn't clear.

I need a way to update our YARN Capacity Scheduler Queues from a script. Currently, we have some processes that run at night, and sometimes the queues are not set properly. I need the script to be able to update the queues. Does the YARN CLI support this? If not, does the Ambari CLI? And if so, how? Thanks!
