Hive 查询在 Tez 上失败，但在从 Beeline 连接时在 Map-Reduce 上成功

Question

I am running into a weird error. I am running a simple select * query with a where clause, following is the summary of query execution status

1. Connecting to Hive from EMR (Tez engine) - succeeding
2. Connecting to Hive from EMR (MR engine) - succeeding
3. Connecting to Hive from Beeline (Tez engine) - failing
4. Connecting to Hive from Beeline (MR engine) - succeeding

I need to solve for point 3. This is the error trace I am getting and unable to find what the root cause of this failure is and what this error log is trying to convey.

Answer 1

I was able to solve this. The problem was I was connecting my application to Hive via JDBC without specifying a user. For queries where simple streaming of data was required, it was succeeding, but where Map-Reduce jobs were being triggered to write to HDFS, the writing operation was failing with the error

Failed to execute tez graph.
    org.apache.hadoop.security.AccessControlException: Permission denied: user=anonymous, access=WRITE, inode="/user":hdfs:hadoop:drwxr-xr-x

To resolve this, I added the user=hadoop; in the JDBC URL and the queries run fine now.

Try invoking beeline ( Tez engine ) as below and then run your query:

beeline -u "jdbc:hive2://<host>:<port>,/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2-batch?tez.queue.name=<yarn-queue-name>"

If above doesn't work then try to fix any issue in SQL. I see 'x' before Where clause in your sql query, that may be the issue. Try to remove that and run your query.

`sf_accounthistory` x WHERE SRC_OP_TYP='NA'

Hope this is helpful
