我在
中复制了所有hadoop文件/opt/vertica/packages/hcat/lib
现在我跑
./hcatUtil --verifyJars --hcatLibPath=/opt/vertica/packages/hcat
我看到了

但是当我跑步的时候
vsql
\cd /opt/vertica/packages/hcat/ddl
\i install.sql
我收到错误

我用Google搜索并发现了这个帖子 https://community.dev.hpe.com/t5/Vertica-Forum/hcatalog-connector/td-p/222733
所以我将/etc/hadoop/conf目录的内容从一个Hadoop节点复制到了我的vertica集群的所有节点。
接下来我做了
\i /opt/vertica/packages/hcat/ddl/uninstall.sql
ALTER DATABASE mydb SET JavaClassPathSuffixForUDx='/etc/hadoop-hdfs-conf/';
\i /opt/vertica/packages/hcat/ddl/install.sql
但这并不能解决问题。我仍然收到相同的错误消息。
EDIT ::
我对此问题进行了更多的重新搜索，我觉得惠普已经将错误的vertica-hcatalogudl.jar与该产品一起发货。这就是为什么这对任何其他人都无效。
如果我这样做
create or replace library public.VHCatalogLib as '/opt/vertica/packages/hcat/lib2/vertica-hcatalogudl.jar' DEPENDS '/opt/vertica/packages/hcat/lib/*.*' language 'java';
我可以看到这个库安装了以下对象
SELECT * FROM USER_LIBRARY_MANIFEST WHERE lib_name = 'VHCatalogLib';
schema_name | lib_name | lib_oid | obj_name | obj_type | arg_types | return_type
-------------+--------------+-------------------+--------------------------------------------------+-----------------+-----------+-------------
public | VHCatalogLib | 45035996371219906 | com.vertica.hcatalogudl.WebHCatConfLoaderFactory | Scalar Function | | Varchar
(1 row)
但是当我读到hcatalog连接器附带的install.sql的源代码时。它说
CREATE SOURCE public.VHCatSource as LANGUAGE 'java' name 'com.vertica.hcatalogudl.HCatalogSplitsNoOpSourceFactory' library public.VHCatalogLib;
GRANT EXECUTE ON SOURCE public.VHCatSource() TO PUBLIC;
CREATE PARSER public.VHCatParser as LANGUAGE 'java' name 'com.vertica.hcatalogudl.HCatalogSplitsParserFactory' library public.VHCatalogLib;
GRANT EXECUTE ON PARSER public.VHCatParser() TO PUBLIC;
但是库从未安装
这就是我们收到错误的原因
无法实例化类com.vertica.hcatalogudl.HCatalogSplitsParserFactory
因为这是因为他们发送了错误的vertica-hcatalogudl.jar文件。
我非常确定HP vertica团队内部有一个vertica-hcatalogudl.jar文件，其中包含使安装成功所需的所有3个对象。
答案 0 :(得分：1)
我能够在HP支持的帮助下解决问题。结果在这里
问题的关键在于我使用的是Vertica 7.1.2-2和Cloudera 5.4.1，它们彼此不兼容。
我将Vertica实例升级到7.2后......事情变得非常顺利。
