How to update the existing record in HDFS?

Big Data Hadoop

Hi Team,

I have uploaded one file in HDFS Cluster. Now I want the existing record. How can I do that?



HDFS follows the approach called Write Once Read Many times. It is not possible to update the existing record in HDFS. However, you are allowed to copy the data including the modifications or updates needed, and remove the previous original copy.
