hadoop - hive -h <主机名>未建立与hive控制台的连接

Question

输入时:
hive -h <hostname>
从hdfs命令行中，我没有直接转到hive控制台。

仍要求输入主机名。

'Choose Hive Server/Metastore Hostname from : <hostname>'
'Enter Hive Server/Metastore Hostname :'

如果使用命令hive -h提交了主机名，则理想情况下，它不应再次要求输入主机名。

Answer 1

使用Hive 3，我从hive -h主机名得到的输出是帮助，没有提到-h选项。使用beeline指定主机名对我有用:

[me@myhost-1 ~]$ beeline -u jdbc:hive2://myhost-2.com:10000
...
Connecting to jdbc:hive2://myhost.com:10000
Connected to: Apache Hive (version 3.1.0.3.0.3.0-192)
Driver: Hive JDBC (version 3.1.0.3.0.3.0-192)
Transaction isolation: TRANSACTION_REPEATABLE_READ
Beeline version 3.1.0.3.0.3.0-192 by Apache Hive
0: jdbc:hive2://myhost-2.com:>

帮助输出还包括其他连接到Hive的直线示例:

Example:
    1. Connect using simple authentication to HiveServer2 on localhost:10000
    $ beeline -u jdbc:hive2://localhost:10000 username password

    2. Connect using simple authentication to HiveServer2 on hs.local:10000 using -n for username and -p for password
    $ beeline -n username -p password -u jdbc:hive2://hs2.local:10012

    3. Connect using Kerberos authentication with hive/localhost@mydomain.com as HiveServer2 principal
    $ beeline -u "jdbc:hive2://hs2.local:10013/default;principal=hive/localhost@mydomain.com"

    4. Connect using SSL connection to HiveServer2 on localhost at 10000
    $ beeline "jdbc:hive2://localhost:10000/default;ssl=true;sslTrustStore=/usr/local/truststore;trustStorePassword=mytruststorepassword"

    5. Connect using LDAP authentication
    $ beeline -u jdbc:hive2://hs2.local:10013/default <ldap-username> <ldap-password>

正确的语法是使用两个连字符，而不是一个:

hive --help
Usage ./hive <parameters> --service serviceName <service parameters>
Service List: beeline cleardanglingscratchdir cli fixacidkeyindex help hiveburninclient hiveserver2 hplsql jar lineage llapdump llap llapstatus metastore metatool orcfiledump rcfilecat schemaTool strictmanagedmigration tokentool version
