转自 http://molisa.iteye.com/blog/1953390 我主要是根据这个说明调整的HUE的时区问题
在使用Cloudera Hue时遇到一问题:
1. 使用Sqoop导入功能时,由于配置错误,使得“保存运行”后Job并不能正常提交,且界面上没有相关提示:
2. 第二个问题是在使用Job Designer设计Sqoop任务,提交时,执行过过程中提示缺少mysql 驱动,虽然驱动已经被我加入到sqoop/lib下,后来才发现,原来安装的时候会将oozie workflow共享依赖的包入到hdfs中,所以我将驱动上传到hdfs://user/oozie/share/lib/sqoop/下,再执行Job就可以了
3. hue oozie 执行sqoop create-hive-table,不能成功在hive metastore中创建table,虽然在sqoop中加入--verbose参数,在执行过程中显示了表示要创建table的DDL语句,但是在hive中show tables;并没有真正创建成功。初步发现的原因,可能是在hue中sqoop没有办法调用起hive client,因为日志的最后并没有打印hive所生成的log.
4. hue oozie中有几个关于时间的设置,都跟时区有关:
5. 当使用MySQL作为集群中Hive的MetaStore和Cloudera Manager Monitor Service的Database的时候,各个节点要安装mysql-connector。
6. 在使用Cloudera Manager部署Hadoop时,由于各节点时钟不统一,会导致服务出现异常,使用NTP server/client可以解决这个问题。
7. Cloudera Manager - Hbase browser couldn‘t connect to localhost:9090
In Hue 2.5.0, there is a new feature called "HBase Browser", it is for user to quickly browsing huge tables and accessing Hbase content. You can also create new tables, add data, modify existing cells and filter data with the autocompleting search bar. If you click on "Hbase Browser" icon and get "API error: couldn‘t connect to localhost:9090", probably you don‘t have a Hbase thrift server running.
In your CM, go to "All Services" -> "hbase1" -> "Instances", then under "Role Instances", click on "Add", choose a node to be "HBase Thrift Server", then start the thrift server. By default, hue connects to itself on port 9090, so make sure hue knows which node is the thrift server.
To start a thrift server from commnad line, just type "hbase thrift start".
