Unknown Space used by Hadoop cluster !

[Prachi Shah <Pr...@lntinfotech.com>]

Hello Hadoop Team,

We have organized 9 node Seismic Hadoop cluster. We loaded a 4gb SegY file on this cluster. To load a file in HDFS (Hadoop distributed File System) we use following command: ./suhdp load -input /usr/share/dumphere/seismic_4GB.segy -output /seismicdata/segy_source/seismic_4GB.su<http://seismic_4GB.su> -cwproot /home/hd/seismicunix So practically it should take space of HDFS(/seismicdata/segy_source/), which in the current scenario is happening. But with the space of HDFS it is consuming the space on NameNode as well(that is 4gb is being consumed of local VM).

So is it that one file is being created on NameNode as well as the effect of load command??


Thanks & Regards,
