Can’t identify hadoop home from Matlab to use Matlab Parallel Toolbox.
I have Matlab2014b + Hadoop installed. The hadoop works well on my CentOS Linux system.
I run the mablab on that CentOS Linux machine. With the commands as follows.
It shows the folder is not a valid Hadop no matter how to change it ( I tried set the directory with hadoop 1.2.1, hadoop 2.5.2, hadoop cloudera distribution; also tried with parameter HADOOP_PREFIX,HADOOP_HOME,MATLAB_HADOOP_INSTALL ).
Anything else I can do to fix this error ?
>> setenv(‘MATLAB_HADOOP_INSTALL’,’/mnt/disk1/data/soft/hadoop-2.5.2′);
>> cluster = parallel.cluster.Hadoop;
Error using parallel.cluster.Hadoop (line 107)
Unable to recognize ‘/mnt/disk1/data/soft/hadoop-2.5.2’ as a valid HADOOP
installation folder. Check that this is the root of your HADOOP installation
folder.
Thanks and Best Wishes.
