HDFS Error when creating a new directory

[#1]

Hi,

When I try to create a new direcoty it gives me the following error:

Cannot perform operation. Note: you are a Hue admin but not a HDFS superuser, "hdfs" or part of HDFS supergroup, "supergroup".

SafeModeException: Cannot create directory /user/cloudera/Source_Data. Name node is in safe mode. The reported blocks 907 needs additional 2 blocks to reach the threshold 0.9990 of total blocks 909. The number of live datanodes 1 has reached the minimum number 0. Safe mode will be turned off automatically once the thresholds have been reached. (error 403)

What can I do to solve this?
