Spark 源码 | 脚本分析总结
主要分享大数据相关的知识，如Spark、Hudi
02-10 1715
最初是想学习一下Spark提交流程的源码，比如 Spark On Yarn 、Standalone。之前只是通过网上总结的文章大概了解整体的提交流程，但是每个文章描述的又不太一样，弄不清楚到底哪个说的准确，比如Client 和 CLuster 模式的区别，Driver到底是干啥的，是如何定义的，为了彻底弄清楚这些疑问，所以决定学习一下相关的源码。因为不管是服务启动还是应用程序启动，都是通过脚本提交的，所以我们先从分析脚本开始。

关于kafka:consumer_offsets日志不能自动清理，设置自动清理规则
linzuo7096的博客
09-03 376
Kafka服务器在运行一段时间后，存储空间耗尽了。剖析Kafka的占用空间状况，发现Kafka主动生成的“__consumer_offset”topic，占用了大量空间，它用于记录每个用户topic的生产偏移量。这一topic实用的清理规定与其余topic不同，某些状况下，它可能始终得不到清理，耗尽服务器资源。策略修改后，无需重启应用，配置等几分钟就生效自动会删除过期文件。--zookeeper zk3:2181即可。
