Replication of Bigdata causes data redundancy in the content. What do you think is the reason that HDFS performs replication? Steve has a Hadoop cluster and there is file of size 514 MB stored in HDFS (Hadoop 2.x) using default block size configuration and default replication factor. Then, calculate how many blocks will be created in total and what will be the size of each block?

Answer #1

Answer:----------
Default block size in Hadoop 2.x is 128 MB.
So, a file of size 514 MB will be divided into 5 blocks ( 514 MB/128 MB) where the first four blocks will be of 128 MB and the last block will be of 2 MB only.
Since, we are using the default replication factor i.e. 3, each block will be replicated thrice.
Therefore, we will have 15 blocks in total where 12 blocks will be of size 128 MB each and 3 blocks of size 2 MB each.

    10) Unlike a signal, which conveys only the occurrence of a particular event and contains no information content, a pipe can be thought of as a scratch file created by a system call. It can be used as a communications channel between concurrently running processes. The interface call to a pipe is similar to that for any file. In fact, the process reads and writes to a pipe just like any file. Unlike files, however, pipes do not represent actual...
