I have DataNode storage /hadoop/htfs/data and I have configured and added 3 disks in addition. I mounted these disks as
/data0 /data1 /data2 . Is there a way to move/split data from
/hadoop/htfs/data to /data0, /data1,/data2 folders ?
Thanks in advance
Unfortunately this is a Hadoop 3.0 feature, described here: https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HDFSDiskbalancer.html
I don't think you can achieve what you want in the current versions. However, this is not necessarily an issue, as the new folders (/data0, /data1, /data2) will be used eventually, so you won't run out of space.
gnovak Many thanks for your answer
