Which component of Hadoop helps to manage the resources across the clusters? In short, it performs scheduling and resource allocation for the Hadoop System.

• MapReduce

• Tez

• YARN

• HDFS

Which component of Hadoop makes it possible to carry over the processing’s logic and helps to write applications which transform big data sets into a manageable one, by making the use of distributed and parallel algorithms?

• YARN

• HDFS

• Pig

• MapReduce

In Hadoop Failure of one node doesn’t affect accessing (read-write operation) of data in datanode. Multiple copies of same Block will be available in other datanode, so the failure of one node will not impact our work and we can make use of a block from other datanode when one of the datanode fails. By default, which the replication factor in HDFS?

• 2

• 3

• 4

• 6
