Getting Error while accessing Hive from command line interface

Some times we  see below error while launching Hive from command line.

Error:

Logging initialized using configuration in file:/etc/hive/2.5.0.0-1245/0/hive-log4j.properties

Exception in thread "main" java.lang.RuntimeException: org.apache.hadoop.security.AccessControlException: Permission denied: user=root, access=WRITE, inode="/user/root":hdfs:hdfs:drwxr-xr-x

 

Here issue will be you are trying to launch the Hive with non HDFS users and it might be Root account.

Below are the steps to solve the problem:

1. Create Root or the users which is using to launch the hive

sudo -u hdfs hdfs dfs -mkdir /user/<<root>>

2. Do the HDFS  ownership change from HDFS to the required user

sudo -u hdfs hdfs dfs -chown -R root:hdfs /user/root
