"Radoop Error: could not upload the necessary components to the directory of HDFS"
I am having problem with this Radoop Error: could not upload the necessary components to the directory of HDFS. It said that the radoop can't upload into the directory ''/tmp/radoop/27eca174758add21906d3b197af684e7/ ' .
So I changed the permission of "'/tmp/radoop/" and also '/tmp/radoop/27eca174758add21906d3b197af684e7/ ' of the namenode in VM, and then I typed in 'hadoop fs -ls /tmp/radoop", results show that the permission had been changed. So I went ahead and re-run the process which has the "Radoop nest", and the same error pop out again, and the permission of the directory "tmp/radoop" is now changed back automatically to the one before.
Could some give me some pointers please ? I am using rapidminer studio with radoop extension to connect to a dummy single node hadoop cluster in local VM.
FYI, i was able to connect the cluster, and also able to explore all the HIVE tables.
Thanks heaps !
