. In Hadop, data is loaded into systems as 'blocks How big it is typically? a. 16MB or 32MB 6. 32MB or 48MB C. 48MB or 96MB d. 64MB or 128MB Which is not correct in Hadoop Fault Tolerance a node fais, the master will detect that faiare and re-assign the work to a different node on the system u. Resrarting a fask requires communication with nódes working on other portions of the data. IF a faited node restarts, it is automatically added back to the system and assigned new tasks node appedrs To be running slowly, the master can redundantly execute another instance of the same task $. Which is not true in Hadoop u. Two core components in Hadoop are HDFS and MapReduce 0. Hadoop Ecosystem includes Pig, Hive, HBase, Flume Oozie, Sqoop, etc GA Hadoop cluster can have only one node . Hadoop is an open-source project overseen by the Apache Software Foundation. In the following answers, which is not true in MapReduce? u. MapReduce is the system used to store data in the Hadoop cluster b. If consists of two phases: Map, and then Reduce C. Between Map and Reduce, there is a stage known as the shuffle and sort d. Each Map task operates on a discrete portion of the overall dataset, Typically one HDFS block_of data 5. From the following answers, which is not true about the basic concepts of HDFS? a. HDFS is a file system written in Java sits on top of a native file system such as ext3, ext4 or xfs b. Provides redundant storage for massive amounts of data using expensive special computers. c. HDFS performs best with a modest number of large files, each file typically 100MB or more d. HDFS is optimized for large, streaming reads of files rather than random reads
