我们正在安装Cloudera CDH4，Ubuntu 12.04 LTS在安装步骤中，我们卡在 hive 元存储启动。我们已按照下载文档中的建议配置了meta-storewith 。MySQL

它给了我们以下错误：

/usr/lib/hive/conf$ sudo service hive-metastore status
 * Hive Metastore is dead and pid file exists

在日志文件中显示以下错误：

ERROR metastore.HiveMetaStore (HiveMetaStore.java:main(4153)) - Metastore Thrift Server threw an exception...
org.apache.thrift.transport.TTransportException: No keytab specified

以下是输出hive-site.xml文件：

我们的主要重点是安装impala. 如果我们使用默认的德比。Hive 元存储运行良好。但是当我们开始时impala-shell。它向我们显示未连接。我们能做些什么来纠正这个问题？

任何人都可以帮助我们解决这个错误。

我认为问题在于您缺少以下参数：

<property>
  <name>hive.metastore.kerberos.keytab.file</name>
  <value>/etc/hive/conf/hive.keytab</value>
  <description>The path to the Kerberos Keytab file containing the metastore thrift server's service principal.</description>
</property>

我看到您确实有 hive.server2.authentication.kerberos.keytab，但似乎这还不够。

将 hive.server2.authentication.kerberos.principal 属性中的“my-domain-name”替换为您的域名。这是 hive 主体中缺少的第三部分。
