问题
we have installed Hadoop 2.5.1 on two Linux (Ubuntu) computers. One computer serves as a name node, the other one as a data node.
Now we want to access the data from a third computer, where Matlab 2014b is installed on a Windows operating system.
We have shared the folder of the Hadoop installation on our Ubuntu machine and set the HADOOP_PREFIX environment variable accordingly within Matlab on our Windows computer.
setenv('HADOOP_PREFIX','\\\myserverip\hadoop');
Now we create a datastore object according to the Matlab documentation:
file = 'hdfs://myserverip:portnumber/foldername/data.csv';
ds = datastore(file);
However, we always get the following error
Error using datastore (line 70)
Failure occured while trying to resolve path 'hdfs://myserverip:portnumber/foldername/data.csv'.
Do you have any ideas?
