Hi@akhtar,

You can change the default block size from the Client. The client will decide what will the block size. So go to your Hadoop configuration folder in the client node. You need to set one property in the hdfs-site.xml file as shown below.

<property>
<name>dfs.block.size</name>
<value>1024</value>
</property>
