How to update the existing record in HDFS

Question

Hi Team,

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

Hi@akhtar,

HDFS follows Write Once Read Many times approach. You can’t UPDATE any existing record in HDFS, but yes, you can surely make another copy of the data (with the modifications/updates) in the HDFS and can remove the previous original copy.
