Hive JDBC - Header sometimes is missing?

[talendtester]

I pull data from multiple tables and always request the column headers.

Sometimes the header is not return in the results, it doesn't happen all the time and the problem happens with different tables.

When I re-run the same job without making changes the header is there again.

Any ideas why this happens?

Other than not requesting the headers, is there a way to avoid this?

Using Talend Big Data 8.0.1.20211109_1610 with HiveJDBC42.jar com.cloudera.hive.jdbc.HS2Driver for Hive 3.1.3000.7.1.7.1000-141.
