HADOOP 444 bigdata 8 Apache Hive 603 - University of Maryland, Baltimore Draw an architectural diagram of Hive with Hadoop and Spark? Show all components. What is the Hive SerDe interface for IO? What is it used for? Describe its benefits? What is the difference between Hive managed tables and external tables? Give examples? Let's look at the fundamental differences between hive internal and external tables now that we've covered the foundations of Hive tables in Hive Data Models. The DESCRIBE FORMATTED table name command in Hive can be used to define whether a table is internal or external, and it will display either MANAGED_TABLE or EXTERNAL_TABLE depending on the table type. Illustrate how EMR could have helped you in the project or in class? ● Using the EMR in our project will help in many things like handling huge data clusters. Workloads based on Apache Hadoop have grown more relevant to all types of projects of all sizes and objectives. As a result, those with the ability to manage these workloads are in high demand. ● Universities have begun to offer classes that teach these principles to the next generation of corporate and IT professionals in an attempt to reach this need. Why would anyone recommend using EMR in replacement of traditional models? ● It has many advantages to recommending the EMR instead of traditional models like ease of use and accessing, elasticity, security, reliability and as well as flexible data stores. ● Apache Spark, Apache Hive, and Apache HBase were all the Hadoop tools supported by Amazon EMR. use of EMR to run computational intelligence technologies like TensorFlow and Apache MXNet, as well as case-specific tools and libraries, employing bootstrap activities. Regarding collaborative innovation, designing Apache Spark tasks, including publishing SQL queries to Apache Hive and Presto,as well as use of EMR Studio, Hue, and EMR Notebooks[12]
