Beeline connection hive2 reports an error permission denied

Error message:

Error: Could not open client transport with JDBC Uri: jdbc:hive2://localhost:10000:
Failed to open new session: 
java.lang.RuntimeException: 
org.apache.hadoop.security.AccessControlException: 
Permission denied: user=anonymous, access=EXECUTE   , inode="/tmp":root:supergroup:drwx------

After trying to add an account and password to hive, it is found that the problem is stored in the last sentence. I am anonymous and the read-write permission of/tmp directory is drwx——

The first character: - indicates that this is a file, d indicates that this is a folder, | indicates that this is a connection file
is divided into three characters in a group
the first three: that is, RWX indicates owner permissions
the middle three: --- user permissions in the same group
the last three: --- other user permissions

permission

represents

value

binary

specific role

R

read

4

00000100

the current user can read the file content and browse the directory

W

write write

2

00000010

the current user can add or modify file contents, and the current user can delete or move directories or files in directories

x

execute

1

00000001

the current user can execute files and enter the directory

Aka, my root account is accessing hive2, so I belong to other user permissions, so I was rejected
solution:

Change the access permission of this file/file directory in the HDFS file system and relax it. The syntax of changing permissions is similar to that of Linux
HDFS DFS - Chmod - R 777/tmp log in with the account password of HDFS
