好久不见. 提交于 2020-03-18 05:13:52
问题 I'm practicing a video tutorial from plural sight about Amazon EMR. I am stuck as i cannot proceed as i am getting this error Not a valid JAR: /home/hadoop/contrib/streaming/hadoop-streaming.jar Please note that tutorial is old and it is using a older Emr version. I am using the latest version is that a problem ? The steps that i took are after entering the credentials in putty 1) Hadoop 2) mkdir streamingCode` 3) wget -o ./streamingCode/wordSplitter.py s3://elasticmapreduce/samples/wordcount

airflow(二)集成EMR使用

1. 准备工作 1.1. 安装并初始化airflow,参考以下文档: https://www.cnblogs.com/zackstang/p/11082322.html 其中还要额外安装的是: sudo pip-3.6 install -i https://pypi.tuna.tsinghua.edu.cn/simple 'apache-airflow[celery]' sudo pip-3.6 install -i https://pypi.tuna.tsinghua.edu.cn/simple boto3 1.2. 配置好本地AWS Credentials,此credential需有启动EMR 的权限。 1.3. 置数据库为外部数据库: 编辑 airflow.cfg 文件,修改数据库连接配置(需提前在数据库中创建好airflowdb 的数据库): sql_alchemy_conn = mysql://user:password@database_location/airflowdb 使用下面的命令检查并初始化: airflow initdb 1.4. 配置executor 为 CeleryExecutor 编辑airflow.cfg 文件,修改executor配置: executor = CeleryExecutor 修改后可以保证相互无依赖的任务可以并行执行

EMR,电子病历(Electronic Medical Record)

六月ゝ 毕业季﹏ 提交于 2020-02-29 08:46:10
电子病历 电子病历(EMR,Electronic Medical Record),也叫计算机化的病案系统或称基于计算机的病人记录(CPR,Computer-Based Patient Record)。它是用电子设备(计算机、健康卡等)保存、管理、传输和重现的数字化的病人的医疗记录,取代手写纸张病历。它的内容包括纸张病历的所有信息。美国国立医学研究所将定义为:EMR是基于一个特定系统的电子化病人记录, 该系统提供用户访问完整准确的数据、警示、提示和临床决策支持系统的能力。 病历是病人在医院诊断治疗全过程的原始记录,它包含有首页、病程记录、检查检验结果、医嘱、手术记录、护理记录等等。电子病历不仅指静态病历信息,还包括提供的相关服务。是以电子化方式管理的有关个人终生健康状态和医疗保健行为的信息,涉及病人信息的采集、存储、传输、处理和利用的所有过程信息。 电子病历是随着医院计算机管理网络化、信息存储介质--光盘和IC 卡等的应用及Internet的全球化而产生的。电子病历是信息技术和网络技术在医疗领域的必然产物,是医院病历现代化管理的必然趋势,其在临床的初步应用,极大地提高了医院的工作效率和医疗质量,但这还仅仅是电子病历应用的起步。 定义 广为接受的电子病历定义由美国医学研究所(IOM)1991年提出,原文如下: "……an electronic patient record that

Create EMR 5.3.0 with EMRFS (s3 bucket) as storage

问题 I'm trying to create EMR 5.3.0 with EMRFS (S3 bucket) as storage. Please provide your general guidance regarding this. Currently i'm using below command for creating EMR 5.3.0 with InstanceType=m4.2xlarge.Which is working fine, but with EMRFS as storage i'm not able to do aws emr create-cluster --name "DEMAPAUR001" --release-label emr-5.3.0 --service-role EMR_DefaultRole_Private --enable-debug --log-uri 's3n://xyz/trn' --ec2-attributes SubnetId=subnet-545e8823, KeyName=XXX --applications Name

delete s3 files from a pipeline AWS

前提是你 提交于 2020-02-25 03:45:41
问题 I would like to ask about a processing task I am trying to complete using a data pipeline in AWS, but I have not been able to get it to work. Basically, I have 2 data nodes representing 2 MySQL databases, where the data is supposed to be extracted from periodically and placed in an S3 bucket. This copy activity is working fine selecting daily every row that has been added, let's say today - 1 day. However, that bucket containing the collected data as CSVs should become the input for an EMR

LIS是什么?

做~自己de王妃 提交于 2020-02-24 15:42:33
在之前的随笔中,大概介绍了医疗系统有哪些,是干什么的,是怎么配合医院业务的。现在就开始主要的说一说我的主要工作业务 — LIS了。 前面说到过LIS(LIMS),名称是实验室信息管理系统,大概可以分解三个部分理解,实验室、信息管理、系统,那么就分解简单说明: 实验室:这里的实验室,不是指广泛认知的学校的化学实验室,物理研究所的物理实验室,而是只的负责医学检测的医学实验室,更细致一点是侧重于化学检验的医学实验室,那么就不仅仅是医院的检验科了,同样包括了众多的第三方实验室(患者,医院属于第一放第二方),比如中国主要的几个第三方实验室:广州金域,武汉康圣达,艾迪康,达安,上海兰卫等等; 信息管理:这个就很浅而易见了,业务数据、信息的采集、存储、管理、分析; 系统:用于支撑上述两点的软件程式; 总结一下,LIS系统就是用于医学实验室进行数据信息的采集、存储、管理、分析的软件系统。 那么,LIS有哪些功能,或者说有哪些模块,分别是干什么的? 那还是要先说一下医学实验室关于检验这一块有哪些部分和要求了。 1. 检验分类:根据检验性质,大致分为 — 临检、生化、免疫、微生物等,其中临检其实应该包括临床生化检验,但是大多数医院会把部分体液检验和非血清检验划归给临检分类,生化主要做血清类检验; 2. 业务分类:根据实验室实际业务区分,大致分为 — 标本采集、标本预处理、标本检验、标本管理、试剂管理

Tool/Ways to schedule Amazon's Elastic MapReduce jobs

…衆ロ難τιáo~ 提交于 2020-01-24 10:26:12
问题 I use EMR to create new instances and process the jobs and then shutdown instances. My requirement is to schedule jobs in periodic fashion. One of the easy implementation can be to use quartz to trigger EMR jobs. But looking at longer run I am interested in using out of box mapreduce scheduling solution. My question is that is there any out of box scheduling feature provided by EMR or AWS-SDK, which i can use for my requirement? I can see there is scheduling in Auto scaling, but i want to
