            Apache Zeppelin configuration for connect to Hive on HDP Virtualbox
            Asked 2022-Feb-22 at 16:53

            I've been struggling with the Apache Zeppelin notebook version 0.10.0 setup for a while. The idea is to be able to connect it to a remote Hortonworks 2.6.5 server that runs locally on Virtualbox in Ubuntu 20.04. I am using an image downloaded from the:

            https://www.cloudera.com/downloads/hortonworks-sandbox.html

            Of course, the image has pre-installed Zeppelin which works fine on port 9995, but this is an old 0.7.3 version that doesn't support Helium plugins that I would like to use. I know that HDP version 3.0.1 has updated Zeppelin version 0.8 onboard, but its use due to my hardware resource is impossible at the moment. Additionally, from what I remember, enabling Leaflet Map Plugin there was a problem either.

            The first thought was to update the notebook on the server, but after updating according to the instructions on the Cloudera forums (unfortunately they are not working at the moment, and I cannot provide a link or see any other solution) it failed to start correctly. A simpler solution seemed to me now to connect the newer notebook version to the virtual server, unfortunately, despite many attempts and solutions from threads here with various configurations, I was not able to connect to Hive via JDBC. I am using Zeppelin with local Spark 3.0.3 too, but I have some geodata in Hive that I would like to visualize this way.

            I used, among others, the description on the Zeppelin website:

            https://zeppelin.apache.org/docs/latest/interpreter/jdbc.html#apache-hive

            This is my current JDBC interpreter configuration:

            So, after many hours and trials, here's a working solution. First of all, the most important thing is to use drivers that correlate with your version of Hadoop. Needed are jar files like 'hive-jdbc-standalone' and 'hadoop-common' in their respective versions and to avoid adding all of them in the 'Artifact' field of the %jdbc interpreter in Zeppelin it is best to use one complete file containing all required dependencies. Thanks to Tim Veil it is available in his Github repository below:

I see that my cluster usage is pretty low so I don't understand why this is happening.

            There is a behavior that is not really well explained in the documentation, the fact that in order to really utilize the cluster and all your additional memory configurations you MUST set up default queues, and you need to specify them when you are going to query, or to connect spark, etc.

            For example, when using tez, you need to use the tez.name.queue={your queue name} in order to fully utilize it, this enables parallelism in yarn.

            For spark, you need to specify the --queue {your queue name} when launching pyspark, or when submitting jobs using the spark_submit.

            In order to use the above, you need to have queues set up in yarn using the hive.server2.tez.default.queues, parameter that you need to set up with the list of default queues for tez. It is important to note that you can create the queues and not list them as default, by doing that you need need to call out the queue manually all the time and the queries are not going to get into any default queue.

            Is there any scenario where we wouldn't want to reuse tez containers?
            Asked 2021-Oct-28 at 07:40

            I started with hive and tez some days back during one of my projects. During that time, I came across this property tez.am.container.reuse.enabled which is recommended to be kept as true by many sites. I understand it's due to :

            • Limiting requests for new containers to RM
            • Reducing the cost of container spin up and hence add to time savings

            But I can't think of any scenario where we would want this property to be disabled. I have been searching online for any such cases but I'm not able to find any.

            Can anyone help me with this?

            ANSWER

            Answered 2021-Oct-28 at 07:40

            In terms of performance, there is no reason not to re-use the containers, Execution Efficiency section of this paper explains very well, and this is why the default value for this parameter is true.

            But, I think there are some cases which might explain why this feature is still configurable;

            • You may want to disable it for workaround purpose. For example, this hive ticket is still unresolved and when tez.am.container.reuse.enabled=false the problematic query works fine. If my production case is critical, instead of being completely blocked, I may prefer running my jobs without re-using the containers.
            • The property may conflict with some other properties, and based on your priority, you may wanna give up on performance. For example in Configure Tez Container Reuse doc, there is a warning which says;

            Do not use the tez.queue.name configuration parameter because it sets all Tez jobs to run on one particular queue.

            • As a last item, I saw another warning on this doc;

            Enabling this parameter improves performance by avoiding the memory overhead of reallocating container resources for every task. However, disable this parameter if the tasks contain memory leaks or use static variables.
