Impact on the System
The Hive on Tez and Hive on Spark functions are affected.
Possible Causes
The Tez or Spark library path is deleted from the HDFS.
Procedure
Check the Tez and Spark library paths.
- Log in to the node where the client is deployed as user root.
- Run the following command to check whether the tezlib or sparklib directory exists in the hdfs://hacluster/user/{User name}/.Trash/Current/ director:
hdfs dfs -ls hdfs://hacluster/user/<username>/.Trash/Current/
For example, the following information shows that /user/hive/tezlib/8.1.0.1/ and /user/hive/sparklib/8.1.0.1/ exist.
host01:/opt/client # hdfs dfs -ls hdfs://hacluster/user/test/.Trash/Current/ Found 1 items drwx------ - test hadoop 0 2019-06-17 19:53 hdfs://hacluster/user/test/.Trash/Current/user
- Run the following command to restore tezlib and sparklib.
hdfs dfs -mv hdfs://hacluster/user/<username>/.Trash/Current/user/hive/tezlib/8.1.0.1/tez.tar.gz /user/hive/tezlib/8.1.0.1/tez.tar.gz
- Check whether the alarm is cleared.
- If yes, no further action is required.
- If no, go to Step 5.
Collect fault information.
