Question

I am trying to access hive table and dump the result back into text file. And when I try to do this, I always get the permission denied? Is there something I am missing?

bash-3.00$ 'select * from ATTRIBUTE_DATA_REALTIME LIMIT 10' > test.txt
bash: test.txt: Permission denied

And what permission I need in this case? Or my query is wrong?

Answer 1

Firstly — you’re missing a hive -e. With what you have now, Bash will look for a program named select * from ATTRIBUTE_DATA_REALTIME LIMIT 10!

But as for the permissions issue, there are two possibilities:

• If test.txt already exists, then you need to run your command as a user that has permission to write to the file. (Use ls -l test.txt to see who owns the file and what the permissions on it are.)
• If test.txt doesn’t already exist, then you need to run your command as a user that has permission to write to the directory containing the file, i.e., the current directory. (Use ls -ld . to see who owns the directory and what the permissions on it are.)
