I am running hive on a standalone machine. Hadoop is running in pseudo-distributed mode. I am running hive query which joins two tables (one table has 7M and another has 51M records and each containing 8 columns). After processing some time, Mapper reaches to zero percentage and then continues to print zero occasionally. Can you please help me to resolve this.
For reference find the logs below.
