| Note: This file includes only those configs which are supposed to have different value from the parent hive/hive-site. |

| The inheritance logic in order to get hive2/hive-site goes like this : |
| |
| 1. We read the hive/hive-site which includes the stack defaults and Stack Advisor recommended values. |
| 2. We take the read hive/hive-site (step 1), and on top of it apply the hive-interactive-site to get |
| hive2/hive-site. |
| |
| Therefore, any config defined here will override the config value read from hive2/hive-site (step 1). |

| <description>If hive.auto.convert.join.noconditionaltask is off, this parameter does not take affect. However, if it |
| is on, and the sum of size for n-1 of the tables/partitions for a n-way join is smaller than this size, the join is directly |
| converted to a mapjoin(there is no conditional task). The default is 10MB. |
