I just wonder whether MapR has the equivalent command line operations for migration purpose in CDH environment.
In CDH I usually migrate stuffs from one HDFS system to another one. The steps of the backup action are as follows:
1) Suppose the HDFS folder /data need to be migrated
2) Make /data snapshottable: hdfs dfsadmin -allowSnapshot /data
3) Create a snapshot: hdfs dfs -createSnapshot /data snapshot
4) Copy the snapshot folder from HDFS to local drive: hdfs dfs -copyToLocal /data/.snapshot/snapshot /tmp/backup
Could someone give me an example on MapR to implement this?
