HDP-2.4.2.0-258使用Ambari 2.2.2.0Sqoop進口HCatalog /蜂巢 - 表不可見
安裝我不得不進口應通過蜂巢，豬，MR以及任何可以訪問多個SQL Server架構第三方（將來）。我決定導入HCatalog。
Sqoop提供了導入到Hive或HCatalog的方法，我想如果我導入HCatalog，同樣的表格可以從Hive CLI，MR和Pig訪問（請評估我的假設）。
問題：
- 如果進口直接攆，將表提供給豬，MR ？
- 如果導入HCatalog，需要通過Hive訪問什麼？
- 是否需要在Hive中預先創建表？如果是，在HCatalog中導入的優點是什麼（我可以直接在Hive中導入）/（在HDFS中導入，然後創建外部表）？
問題： 我希望達到的一個步驟如下：
- 導入數據（從SQL Server表）
- 避免「預創建」或寫創建語句對於這些表（其中有100個）
- 以ORC格式存儲表
- 將此數據存儲在自定義HDFS路徑say/org/data/schema1，/ org/data/schema2等等（因爲Sqoop說，它（--target-DIR /這是不可能的 - 倉庫 - DIR）
我執行以下命令：
-bash-4.2$ sqoop import --connect 'jdbc:sqlserver://<IP>;database=FleetManagement' --username --password --table SettingAttribute -- --schema Administration --hcatalog-home /usr/hdp/current/hive-webhcat --hcatalog-database default --hcatalog-table SettingAttribute --create-hcatalog-table --hcatalog-storage-stanza "stored as orcfile"
源表包含109條記錄，那些被取：

有一些授權問題？
我檢查了var/log，但沒有Sqoop，Hive-Hcatalog和Hive存在，我如何查看授權問題並修復它？
@dev感謝編輯，我無法格式化代碼:) –
