number of cores per worker node

you use ambari rest api number of worker nodes.

password=<> clustername=<> #worker nodes   curl -u admin:$password -ss -g "https://$clustername.azurehdinsight.net/api/v1/clusters/$clustername/services/hdfs/components/datanode">worker.txt cat worker.txt |grep total_count|awk -f: '{print $2}'|sed 's/\,//g'

ram per worker node

do mean vm's max ram? if yes, every worker node vm should have same ram. vm's ram , cores decided vm's size. more information please refer link. if want achieve script. suggest write configure file, such as

standard_ds1_v2 1   3.5  standard_ds2_v2 2   7

you core , mem using awk, easy. such example.

mem=`cat configure.txt|grep "standard_ds1_v2"|awk '{print $3}`

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
