hi , when i do CDH5.10-1, i facing some problems and can't understand what to do ,can anyone tell me ,please.
suppose that i am a common user (not superuser=root) , and i don't know the password about log in root user .
my question 1 :
can i have any way to solve the proble that need me to insert the password when i use command "su hdfs",because i have no idea about the default password
my question 2 :
i do some work , and i see some people say that the default password is on purpose . because common users don't need having the permission to log in HDFS.
so , if i'm a common user called "permission", and i don't have any directory in HDFS just like the shot
but i want to create a directory just like other users , what can i do??
( if i use "hdfs dfs -mkdir /user/permission" it will show permission denied)
can anyone tell me what can i do???? thx~
>> Ask your administrator. Not sure he is willing to give you that.
