Introduction

Hive is a popular data warehousing and SQL-like query language for Hadoop. It allows users to write complex queries and analyze large datasets stored in Hadoop Distributed File System (HDFS). However, when running Hive on Windows 10, users may encounter an error message indicating that the 'posix:permissions' attribute is not supported. In this article, we will discuss the possible causes of this error and provide solutions to resolve it.

Understanding the Error

The error message 'java.lang.UnsupportedOperationException: 'posix:permissions' not supported as initial attribute' indicates that Hive is trying to use the 'posix:permissions' attribute, which is not supported on the current operating system. This attribute is used to set permissions for files and directories in HDFS.

Possible Causes

There are several possible causes of this error:

Unsupported Operating System: Hive does not support the 'posix:permissions' attribute on Windows operating systems. This attribute is only supported on Unix-based systems like Linux and macOS.
Incorrect Configuration: The Hive configuration file may be set to use the 'posix:permissions' attribute, which is not supported on Windows.
Hadoop Version: The version of Hadoop being used may not support the 'posix:permissions' attribute.

Solutions

To resolve the error, you can try the following solutions:

Solution 1: Update Hadoop Version

If you are using an older version of Hadoop, you may need to update to a newer version that supports the 'posix:permissions' attribute. You can download the latest version of Hadoop from the Apache website and follow the installation instructions.

Solution 2: Disable 'posix:permissions' Attribute

You can disable the 'posix:permissions' attribute in the Hive configuration file. To do this, follow these steps:

Open the Hive configuration file (hive-site.xml) in a text editor.
Locate the fs.permissions.enabled property and set it to false.
Save the changes to the file.

Solution 3: Use a Different File System

If you are using HDFS as the file system, you can try using a different file system that supports the 'posix:permissions' attribute. For example, you can use the Local File System (LFS) or the Distributed File System (DFS) provided by Hadoop.

Solution 4: Run Hive in Local Mode

You can run Hive in local mode, which does not use HDFS and therefore does not require the 'posix:permissions' attribute. To run Hive in local mode, follow these steps:

Open a terminal or command prompt.
Navigate to the Hive installation directory.
Run the following command: hive -hiveconf hive.metastore.uris=null -hiveconf hive.exec.local.scratchdir=/tmp

Conclusion

The 'java.lang.UnsupportedOperationException: 'posix:permissions' not supported as initial attribute' error in Hive on Windows 10 can be caused by several factors, including an unsupported operating system, incorrect configuration, or an outdated Hadoop version. To resolve the error, you can try updating the Hadoop version, disabling the 'posix:permissions' attribute, using a different file system, or running Hive in local mode.

Troubleshooting Tips

Check the Hive configuration file for any settings that may be causing the error.
Verify that the Hadoop version being used supports the 'posix:permissions' attribute.
Try running Hive in local mode to see if the error persists.
Check the Hive logs for any error messages that may provide more information about the issue.
