I've implemented a PHP script following this documentation and i correctly listed the stored databases; unfortunately i can not query any of the tables, receiving this error:
[message:protected] => HiveExecuteException: Execute Error:: Query returned non-zero code: 9, cause: FAILED: Execution Error, return code -101 from shark.execution.SparkTask query:: select * from HIVE_TABLE_NAME
But in Hive CLI the query shows the results properly.
Waiting for your feedback, thank you in advance.
Unexpectedly today the problem is gone.
Thank you.
