Hive query with where clasue throwing error using Squirrel SQL client

Expert Contributor

When I run a simple query with WHERE clause from hive, it returns result. But, the same query using Squirrel client throws error. If I remove where clause, it works on SquirreL and Hive both. Any idea?

On SquirreL SQL Client:
select * from my_table where col_id=11500 limit 5;

Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.tez.TezTask
SQLState:  08S01
ErrorCode: 1
hive> select * from table where col_id=11500 limit 5;

I figured out what was wrong. I had no UserId/password setup on Linux and Hadoop for the Squirrel SQL service user. I was not passing userID/password, while making a connection using JDBC.

SquirreL does not complaint if you do not pass a UserID and Password. It will let you connect to hive using JDBC URL.

Running "SELECT * FROM <table>" does not need to start a job and that's why SquirreL can run this query using JDBC only without any issue. But, for running a query like "SELECT * FROM <table> WHERE <condition>" needs to start a map/reduce job, which, further needs a linux and hadoop account in the cluster.

I created a service account for SquirreL client on Linux and Hadoop and used the credential in SquirreL configuration for the connection and everything worked as expected.

I'm wondering whether you loaded all libraries correctly, check for missing jars, error code signifies it's coming from database https://dev.mysql.com/doc/refman/5.5/en/error-messages-server.html
