hdfs dfs -mkdir, No such file or directory
hadoop, hdfs
Solution
It is because the parent directories do not exist yet either. Try `hdfs dfs -mkdir -p /user/Hadoop/twitter_data`. The `-p` flag indicates that all nonexistent directories leading up to the given directory are to be created as well.

Problem
Hi I am new to hadoop and trying to create directory in hdfs called twitter_data. I have set up my vm on softlayer, installed & started hadoop successfully. This is the commend I am trying to run: hdfs dfs -mkdir hdfs://localhost:9000/user/Hadoop/twitter_data And it keeps returning this error message: ``` /usr/local/hadoop/etc/hadoop/hadoop-env.sh: line 2: ./hadoop-env.sh: Permission denied 16/10/19 19:07:03 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable mkdir: `hdfs://localhost:9000/user/Hadoop/twitter_data': No such file or directory ``` Why does it say there is no such file and directory? I am ordering it to make directory, shouldn't it just create one? I am guessing it must be the permission issue, but I cant resolve it. Please help me hdfs experts. I have been spending too much time on what seems to be a simple matter. Thanks in advance.
