We are using CDH and we are planning to save some space for the future incoming data on HDFS. So, we were thinking if we could compress/Zip old HDFS data so that we could reduce some space.
1. Is Compression or zipping of HDFS files possible ?
2. Can we compress it and store it on local file system or HDFS file system
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.
4. Will it compress even with the original file path or metadata ?
Thanks a ton !
