无法在Vertica的

安装HCatalog连接器

我复制了所有的Hadoop文件无法在Vertica的

/opt/vertica/packages/hcat/lib

现在，当我运行

./hcatUtil --verifyJars --hcatLibPath=/opt/vertica/packages/hcat

我看到

但是当我运行

vsql 
\cd /opt/vertica/packages/hcat/ddl 
\i install.sql

我得到一个错误

我用Google搜索，发现这个线程 https://community.dev.hpe.com/t5/Vertica-Forum/hcatalog-connector/td-p/222733

所以我复制/etc/hadoop/conf目录的内容从Hadoop的节点之一的所有节点我Vertica集群。

下一个我做

\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

但这并不解决问题。我仍然收到相同的错误信息。

编辑::

我没有对这个问题更重新搜索，我觉得，惠普已经发运了错误的Vertica的-hcatalogudl.jar的产品。这就是为什么这不适用于其他人。

如果我做

create or replace library public.VHCatalogLib as '/opt/vertica/packages/hcat/lib2/vertica-hcatalogudl.jar' DEPENDS '/opt/vertica/packages/hcat/lib/*.*' language 'java';

我可以看到下面的对象由该libary

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)

安装，但是，当我读到install.sql的源代码，其自带的hcatalog连接器。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;

但图书馆从未安装
