Spark-shell does not support yarn cluster and starts in Yarn client modeSpark-shell--master=yarn--deploy-mode=clientStart the log with the following error messagewhere "neither Spark.yarn.jars nor Spark.yarn.archive is set, falling back to uploading libraries under Spark_home", was just a warning to the official The explanations are as follows:Probably said: If S

The Spark cluster is required for the recent completion, so the deployment process is documented. We know that Spark has officially provided three cluster deployment scenarios: Standalone, Mesos, YARN. One of the most convenient Standalone, this article mainly on the integration of YARN deployment plan.

In Mesos and yarn, the dominant Resource fairness algorithm (DRF) is used, unlike Hadoop slot-based fair and scheduler capacity, which are based on scheduler implementations, Paper reading: Dominant Resource fairness:fair Allocation of multiple Resource Types.Consider the issue of fair resource allocation in a system that includes multiple resource types (mainly CPU and mem), where different users have different requirements for resources.

to fundamentally address the performance bottlenecks of the old MapReduce framework, and to promote the longer-term development of the Hadoop framework, starting with the 0.23.0 release, Hadoop's MapReduce framework was completely refactored and changed radically. the new Hadoop MapReduce framework is named MapReduceV2 or Yarn,Yarn's reconstruction of Mapreducev1, the fundamental idea is to separate the Jobtracker two main functions into a separate

Typical examples are Google dremel, Apache drill, and cloudera impala, which features high performance (compared with hive and other systems), but Scalability (including cluster Scale Expansion and SQL type support diversity) and poor fault tolerance. Google described the applicable scenarios of dremel in the dremel paper (see reference [4]) as follows: "Dremel is not intended as a replacement for Mr and is often used in conjun

Scalability: In contrast to Jobtracker, each application instance, here can be said to be a mapreduce job has a managed application management that runs during application execution. This model is closer to the original Google paper.
