Uncompress gz file from HDFS to HDFS – Hadoop:

$hadoop fs -text /hdfs_path/compressed_file.gz | hadoop fs -put - /hdfs_path/uncompressed-file.txt

Only Disadvantage: The only drawback of this approach is that in HDFS the data will be merged into a single file even though the local compressed file contains more than one file.
