我们正在HDI4.0上使用Hive3.1.x集群，其中1个是llap，另一个只是Hive3.1.x集群。
我们在两个集群上都创建了一个托管表，行数为 272409 .
在两个群集上合并之前

+---------------------+------------+---------------------+------------------------+------------------------+
| order_created_date  | col_count  | col_distinct_count  |        min_lmd         |        max_lmd         |

``` `Based on the delta, we'd perform a merge operation (which updates 17 rows).` 在hive llap群集上合并后（压缩前）

+---------------------+------------+---------------------+------------------------+------------------------+
| order_created_date | col_count | col_distinct_count | min_lmd | max_lmd |
+---------------------+------------+---------------------+------------------------+------------------------+
| 20200615 | 272409 | 272392 | 2020-06-15 00:00:12.0 | 2020-07-27 22:52:34.0 |
+---------------------+------------+---------------------+------------------------+------------------------+

在hive llap群集上合并后（压缩后）

+---------------------+------------+---------------------+------------------------+------------------------+
| order_created_date | col_count | col_distinct_count | min_lmd | max_lmd |
+---------------------+------------+---------------------+------------------------+------------------------+
| 20200615 | 272409 | 272409 | 2020-06-15 00:00:12.0 | 2020-07-27 22:52:34.0 |
+---------------------+------------+---------------------+------------------------+------------------------+

仅在配置单元群集上合并后（不压缩增量）

+---------------------+------------+---------------------+------------------------+------------------------+
| order_created_date | col_count | col_distinct_count | min_lmd | max_lmd |
+---------------------+------------+---------------------+------------------------+------------------------+
| 20200615 | 272409 | 272409 | 2020-06-15 00:00:12.0 | 2020-07-27 22:52:34.0 |

这就是观察到的不一致
但是，在hivellap上压缩表之后，结果集不一致并没有出现，两个集群都返回相同的结果。 `We thought it might be due to either caching or llap issue, so we restarted the hive-server2 process which will clear the cache. The issue is still persistent.` We also created a dummy table with same schema on just hive cluster and pointed the location of that table to that of llap one, which in turn is producing result as expected. `We even queried on spark using**Qubole spark-acid reader**(direct hive managed table reader), which is also producing expected result` 这太奇怪了，有人能帮上忙吗。
