This error message indicates that there was a failure while executing a Tez graph in Hive. The specific error is related to the failure to write a resource file (hadoop-lzo-0.4.20.jar) to HDFS.
The error suggests that a previous writer likely failed to write the resource file, and the current execution is also unlikely to write it successfully.
To resolve this issue, you can try the following steps:
- Check the HDFS cluster's health and ensure that it is functioning properly.
- Verify the permissions and ownership of the HDFS directory where the resource file is supposed to be written. Ensure that the user executing the Hive query has sufficient permissions to write to that directory.
- Check if there are any issues with the network connectivity between the Hive server and the HDFS cluster. Ensure that the network connection is stable and reliable.
- If the resource file (hadoop-lzo-0.4.20.jar) is required for your query, make sure it is available and accessible. You can try copying the file to a local directory on the Hive server and provide the local path instead of the HDFS path in your Hive query.
If the issue persists, you may need to investigate further and provide more details about your Hive configuration, the specific query you are running, and any other relevant error messages or logs
