In an HDFS system which block size you would choose and whyamong 16 KB or 64 MB, if the file named 'abc.txf is given to youwith size of 20,000MB. Given suitable reasons for your answers ineach case of 16KB and 64MB

When choosing the block size for an HDFS system, it is important to consider the given file size and the characteristics of the system. In this case, we have a file named 'abc.txf' with a size of 20,000MB.

If we choose a block size of 16KB, it means that each block will have a size of 16KB. This small block size can be beneficial in scenarios where we have many small files. However, in the case of a large file like 'abc.txf' with a size of 20,000MB, using a block size of 16KB would result in a large number of blocks. This can lead to increased metadata overhead and slower processing due to the need to manage and process a large number of blocks.

On the other hand, if we choose a block size of 64MB, each block will have a size of 64MB. This larger block size is more suitable for handling large files. With a file size of 20,000MB, using a block size of 64MB would result in fewer blocks compared to a block size of 16KB. This reduces the metadata overhead and improves processing efficiency as there are fewer blocks to manage and process.

Therefore, in this case, it would be more appropriate to choose a block size of 64MB for the HDFS system, considering the size of the file 'abc.txf' and the associated benefits of a larger block size.
