中文——自我介绍
面试官您好,我是***,毕业于*大学计算机科学与技术专业,今年22岁。
首先介绍一下我掌握的专业技能,比较熟悉Java,包括Java集合框架,JVM的内存模型,JVM类加载机制,JVM垃圾回收等内容;在大数据组件中,比较熟悉hadoop,包括HDFS的读写原理及故障恢复机制,yarn的任务提交流程,mapreduce的shuffle机制等。在数据采集方面熟悉flume、sqoop采集日志数据及业务数据。此外熟悉分布式消息队列kafka,zookeeper,Hive,HBase,mysql等。
接下来介绍一下我的两个项目。
第一个项目是离线数据仓库,使用flume采集用户行为数据到kafka做削峰处理再到hdfs中,使用sqoop采集业务数据到hdfs中与用户行为数据一共形成ods层,然后使用hive进行过滤、整合、转化、分析形成最终形成dwd,dim,dws,dwt层
第二个项目是实时数据仓库,使用flinkCDC将日志数据及业务数据发送到kafka形成ods层,再对ods层数据进行分流形成dwd,dim维表层,dwd层关联维表层形成dwm层,最后根据某个主题将多个事实数据进行轻度聚合,形成主题宽表。
以上就是我的自我介绍。
