the container. It is the responsibility of AM to monitor the working status of the container. 4. Once The AM is-is-to-be, it should unregister from the RM and exit cleanly. Once am has done all the work, it should unregister the RM and clean up the resources and exit. 5. Optionally, framework authors may add controlflow between their own clients to report job status andexpose a control plane.7 ConclusionThanks to the decoupling of resource management and programming framework, yarn provides: Be

However, a unified control layer for all workloads on the kubernetes can simplify cluster management and increase resource utilization.Apache Spark 2.3, with native kubernetes support, combines the large-scale data-processing framework with two famous Open-source projects; and Kubernetes.The Apache Spark is an essential to

mainly shuffle use, Here are two scenarios, shuffle write and shuffle read,write occupy the memory strategy is more complex, if it is the general sort, mainly with the heap memory, if it is tungsten sort, Is the way in which the out-of-heap memory is combined with the memory in the heap (if the external memory is not enough), and whether the sort is a normal sort or tungsten is determined by spark.For shuffle read, the main use is in-heap memory.

After integrating the Scala environment into eclipse, I found an error in the imported spark package, and the hint was: Object Apache is not a member of packages Org, the net said a big push, in fact the problem is very simple;Workaround: When creating a Scala project, the next step in creating the package is to choose:Instead of creating a Java project that is the package type of the Java program, and then
calculate the small data, observe the effect, adjust the parameters, and then gradually increase the amount of data for large-scale operation by different sampling scales. Sampling can be done via the RDD sample method. WithThe resource consumption of the cluster is observed through the Web UI.1) Memory release: Preserves references to old graph objects, but frees up the vertex properties of unused graphs as soon as possible, saving space consumption. Vertex release through the Unpersistvertice
The creation of an RDDTwo ways to create an rdd:1) created by an already existing Scala collection2) created by the data set of the external storage system, including the local file system, and all data sets supported by Hadoop, such as HDFs, Cassandra, HBase, Amazon S3, etc.The RDD can only be created based on deterministic operations on datasets in stable physical storage and other existing RDD. These deterministic operations are called transformations, such as map, filter, GroupBy, join.The c
