HiveServer2运行慢，不定时宕机，问题排查1. 问题描述2. 原因分析（分析方法）3. 解决方案总结
1. 问题描述
大数据组件 HiveServer2性能问题，有时运行很慢，几天宕机一次，需要不定时重启。
2. 原因分析（分析方法）分析思路： 运行慢时，jstat 查看 gc回收情况

更深层次的问题：16G内存为什么不够？
至于16G内存为什么会不够，需要做个heap dump分析，这个jvm宕机了，没有写dump文件。。。下次喽…
3. 解决方案解决方案： 调大内存
如果是社区版：在$HIVE_HOME/conf/hive-env.sh 中，修改Xmx大小，翻倍配置。
如果是cloudera管理，在管理页面改
总结
分析程序古怪问题，其中一种思路： 黑盒分析。直接使用JVM工具，看看jvm内部各个内存区的运行情况，确认问题后，在fix。
这里有个问题：我这次是运气好，jstat看到正在FullGC, 如果是刚重启完，jvm没什么问题，但很确定过几天会有问题，如何处理这种场景，给大家思考一下？
