Exception when loading data to HDFS library

[vasireddyajay]

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?

ERROR: An I/O error has occurred on file MOLHDFS.DEP_DIM.DATA.

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
