Error while populating HIVE table with HDFS data

junnnninho — Mon, 18 Apr 2016 04:12:06 GMT

Hello there,

I am getting the error below while trying to populate a HIVE table from the HIVE view with an HDFS file:

LOAD DATA INPATH '/employees/part-m-00000' OVERWRITE INTO TABLE temp_employees;

The part-m-00000 file is the result of successful Sqoop import of a MySQL table into HDFS.

I suspect this is a permission issue, but I am not sure where to go to fix it.

Any help appreciated.

Yes, you have a permission problem on your input file:

Permission denied: user=admin, access=WRITE, inode="/employees/part-m-00000":hdfs:hdfs:drwxr-xr-x

As an immediate remedy you can change permissions, for example:

su - hdfs -c "hdfs dfs -chmod -R +w /employees/"

Long term, it's the best to run all you commands using an end-user account (not hdfs, root, admin etc.), In Sandbox-2.4 you can use a user called "maria-dev". So when you run sqoop, do "su - maria_dev" first, and run your commands, and when you use Ambari views, login into Ambari also as maria_dev. In this way you can avoid permissions issues.

Edit: Before doing "su - maria_dev", create the user "maria_dev" on the local OS, run this as root: "useradd maria_dev". This is a one-time prep operation.
