So, we were thinking if we could compress/Zip old HDFS data so that we could reduce some space.</P><P>&nbsp;</P><P>1. Is Compression or zipping of HDFS files possible ?</P><P>2. Can we compress it and store it on local file system or HDFS file system</P><P>3. If yes, how to uncompress the data and keep it back to the same HDFS in future with the exact Metadata information or path where it existed before.&nbsp;</P><P>4. Will it compress even with the original file path or metadata ?</P><P>&nbsp;</P><P>Thanks a ton !&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P> Wed, 13 Jan 2021 12:08:55 GMT sass 2021-01-13T12:08:55Z
