Presto with Kubernetes and S3 Deploy Apache Hive Metastore. Presto on Kubernetes Architecture. As the enterprise environment gravitates towards Kubernetes at an accelerating pace, the industry is urgently looking for a solution that will enable Hive to run on Kubernetes. Managed Kubernetes cluster by AWS. ABOUT THIS COURSE. CoreHive is proud to announce that we are now a Kubernetes Certified Service Provider (KCSP). Here is a trick to avoid such case, I have written a simple wrapper class in which spark thrift server will be invoked, let’s see the wrapper class `SparkThriftServerRunner`: This class will be called to run spark thrift server in spark submit shown below: To build spark thrift server uber jar, type the following command in examples/spark-thrift-server : As mentioned before, spark thrift server is just a spark job running on kubernetes, let’s see the spark submit to run spark thrift server in cluster mode on kubernetes. To deploy Spark and the sample application, create a Kubernetes Engine cluster by running the following commands: gcloud config set compute/zone us-central1-f gcloud container clusters create spark-on-gke --machine-type n1-standard-2 Download sample code. It is not easy to run Hive on Kubernetes. A new DAGAppMaster Pod is created and the query resumes quickly. Hive: a data warehouse software that facilitates reading, writing, and managing large datasets residing in distributed storage using SQL. Ressourcen.

Such a connector allows you to either access an external Metastore or use built-in internal Presto cluster Metastore as well. On Hadoop, it suffices to copy the binary distribution in the installation directory on the master node. Also the latest version of Minikube (0.19.1 at the moment) uses advanced syntax for deploying DNS addon, which is not supported in Kubernetes 1.5. To get started we need a Google account. Spark is mainly used in coordination with Kafka to handle the streaming use case. A command line tool and JDBC driver are provided to connect users to Hive. As this guide uses Docker and Kubernetes from GCP, you do not need get into the hassle of installing Docker and Kubernetes on your system. Kubernetes is an open source software that allows you to deploy and manage containerized applications at scale. Configure a Presto data source in Denodo Platform. 19 mins ago . One more thing which is necessary to us is build docker image of spark, let’s build spark docker image which will be used to run spark thrift server and another spark jobs later: Now, almost ready to install spark thrift server, let’s create spark thrift server service to which jdbc client can connect: Spark submit does not allow default spark thrift server to be run in cluster mode on kubernetes.

After completing this job, some data will be saved on S3 bucket, and parquet table and delta lake table in Hive will be created to query. Step 0: Need Google Account for GCP. Kubernetes (K8s) eases the burden and complexity of configuring, deploying, managing, and monitoring containerized applications. Even though Azkaban provides several job types like hadoop, java, command, pig, hive, etc, I have used just command job type for most of cases. Structure can be projected onto data already in storage. Managed Spark on K8S¶. Would you want Kubernetes to manage your HDFS data nodes (which would require associating pods with the nodes that have disks), or would you use some other storage solution? With command job type, you can just type some shell commands to run jobs. Component 2: Presto. 2. If you have no such S3 bucket and NFS available, you can install them on your kubernetes cluster manually like me: Spark Thrift Server as Hive Server2 needs Hive metastore.
