I have few questions regarding the Lustre Filesystem with 1 MDS/MDT on the
same machine, 12 OSTs configured with LVM for 2 OSS total and 4 Lustre
Client running Hadoop(1 namenode and 3 datanode). Hadoop using Lustre
instead of HDFS.
Question: I have created LVM for OSTs instead of physical hard disk? How is
it going to affect my wordcount example running on 1 Namenode and 3
Datanodes. Say, if its 30 min for 18GB plain data wordcount to finish,
using physical hard disk will lessen the time?
Question: I would like to use other dataset like wikipedia dump instead of
simple wordcount. How shall I put the
In case of HDFS, I simply loaded into HDFS through -copyFromLocal command.
Please suggest for Lustre.
