Exception when loading data to HDFS library

Hi,

I am exploring, how I can add a dataset to HDFS folder. For that, I created corresponding library and gave sufficient rights. However, on the physical hadoop folder, I have write problems. Could you please guide me how to give write permissions to hadoop folder. Doesn't the management console create it when declaring the HDFS library?

The HDFS path in management console for the library is given as dev/test.

Thanks.

Kind regards,

Hi,

the problem is solved by giving necessary rights for the user group on the hadoop filesystem.

hadoop fs -ls /

hadoop fs -chmod myuser /dev

Apache Hadoop;

Thanks to SAS developer Wesley on this regard.

Cheers,

Ajay
