Sqoop导入到HCatalog/Hive-表不可见

Question

HDP-2.4.2.0-258安装使用Ambari2.2.2.0

我必须导入几个SQL Server模式，这些模式应该可以通过Hive、Pig、MR和任何第三方（将来）访问。我决定在HCatalog中导入。

Sqoop提供了导入到Hive或HCatalog的方法，我想如果我导入到HCatalog，同一个表将可以从Hive CLI、MR和Pig访问（请评估我的假设）。

问题：

• 如果直接进口到蜂巢，猪可以使用这个桌子吗

问题：我希望一步到位：

• 导入数据（从SQL Server表中）

我执行了以下命令：

-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条记录，这些记录被提取：

我在HCatalog（或蜂巢）中看不到任何东西

是否存在授权问题？

我检查了var/log，但Sqoop、Hive-Hcatalog和Hive都不存在，我如何查看授权问题并修复它？

Answer 1

嗯，我不确定这是授权问题还是仅仅是解析问题，或者两者兼而有之。我做了以下工作，它起作用了：

做了一个su蜂巢

执行了以下命令（可能，----schema应该是最后一个arg，Sqoop只是忽略/中断之后！）
