CDH Hive raise：无法实例化 org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
CDH Hive raise: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
我在两台服务器上安装了CDH 6.2，device1为主。
CM web UI 中没有任何错误，但是，当我 运行 hive command-line: show databaes; in device1 时，出现如下异常：
dennis@device1:~$ hive

但是，当我运行 hive 命令行时，device2 上没有任何异常。
另外在Hue
上也是正常的
您的设备 1 上可能没有 Hive 服务的网关，只有您的设备 2 可能也有 Hive MetaStore。另见 How Hive Configurations are Propagated to Hive Clients（强调我的）：
Because the Hive service does not have worker roles, another mechanism is needed to enable the propagation of client configurations to the other hosts in your cluster. In Cloudera Manager gateway roles fulfill this function. Whether you add a Hive service at installation time or at a later time, ensure that you assign the gateway roles to hosts in the cluster. If you do not have gateway roles, client configurations are not deployed.
您的设备 1 没有客户端配置，因此无法与 Hive MetaStore 建立连接。
您还应该检查在复制输出开始时收到的错误消息（强调我的）：
/opt/cloudera/parcels/CDH-6.2.0-1.cdh6.2.0.p0.967373/bin/../lib/hive/conf/hive-env.sh: line 24: /opt/cloudera/parcels/CDH-6.2.0-1.cdh6.2.0.p0.967373/lib/hbase/hbase-hadoop2-compat.jar: Permission denied
配置单元用户无法访问某些目录可能存在权限问题。
最后一点是你应该切换到直线。由于输出中的以下消息显示不建议使用 Hive CLI：
WARNING: Hive CLI is deprecated and migration to Beeline is recommended.
另请参阅 Migrating from Hive CLI to Beeline: A Primer，Cloudera 2014 年的指南：
Recently, the Hive community (with Cloudera engineers leading the charge) introduced HiveServer2, an enhanced Hive server designed for multi-client concurrency and improved authentication that also provides better support for clients connecting through JDBC and ODBC. Now HiveServer2, with Beeline as the command-line interface, is the recommended solution; HiveServer1 and Hive CLI are deprecated and the latter won’t even work with HiveServer2.
