Question

Hi Guys,

I am trying to create a file in Hadoop Cluster. But it is showing me the below error.

$ hadoop fs  -D dfs.block.size=5120000000000000 -touchz abcdefd.txt /
touchz: java.io.IOException: java.lang.IllegalArgumentException: Unexpected value for the block size

Hi@akhtar,

You are trying to create a block size in Hadoop that is not supported. According to my knowledge you can create a block size of 256 Terabytes maximum. But in your case your block size is more then that. So choose a block size accordingly.
