How long does the Hadoop Resource Manager store the application information?

社会主义新天地 提交于 2019-12-23 04:32:53
问题 we read resource usage from various users and applications from the Hadoop Resource Manager using the official REST api. Our problem is that the application history does not last long enough so that it returns -1 values for used cores, memory and containers. We'd like to extend the duration that yarn stores the data but we don't know where to set the value. 回答1: You should check your mapred-site.xml and look at mapreduce.jobhistory.max-age-ms . As stated in: https://hadoop.apache.org/docs

折月煮酒 提交于 2019-12-23 04:19:11
问题 Have a number of image files resources e.g. image01.png, image02.png.... I have have set up resource folders with different locale/resolution/orientation qualifiers e.g. /res/drawable-en-mdpi-port /res/drawable-en-mdpi-land /res/drawable-fr-hdpi-port........... Image files in each differ (aspect ratio/resolution/locale-specfic image) Is there anyway to programatically determine which actual resource file is in use in application? Would be useful to me for testing to send it out on debug log,

Why is it bad practice to make multiple database connections in one request?

北城余情 提交于 2019-12-23 04:07:36
问题 A discussion about Singletons in PHP has me thinking about this issue more and more. Most people instruct that you shouldn't make a bunch of DB connections in one request, and I'm just curious as to what your reasoning is. My first thought is the expense to your script of making that many requests to the DB, but then I counter myself with the question: wouldn't multiple connections make concurrent querying more efficient? How about some answers (with evidence, folks) from some people in the

问题 I have spent the last hours trying to figure out how to access static ressources from a jsp in Spring mvc web application.

问题 I have a gameplay screen, with a link to return to a players' stat page. My test user id is 0, and the mine id is 1. So the url of the gameplay screen is /users/0/mines/1 The button from gameplay back to player stats looks like this: <%= link_to "Home", user_path, id: 'link-to-hq' %> User_path seems to be correct, but when I click it, I have the error: Couldn't find User with 'id'=1 def find_user @user = User.find(params[:id]) end (This is my private find user method from my user's controller

Android: Are raw resources stored locally on the filesystem?

拈花ヽ惹草 提交于 2019-12-22 18:47:08
问题 I am analyzing an APK, and see a set of .txt resources in the /res/raw/ directory of the application. After installing the application on an emulator, I would expect to see those same files in the /data/data/[app]/files directory, but they do not seem to exist. Where are the raw resources stored? Are raw resources generated at application runtime somewhere else on the filesystem? Or when they are accessed, is it dynamically from the local .apk file? Thanks. 回答1: Raw resources (and really, all

How would I use a pack uri resource with media player?

时间秒杀一切 提交于 2019-12-22 17:36:19
问题 I have some very simple code which just needs to play a sound with a specified volume, as follows : var mp = new MediaPlayer(); mp.Open(uri); mp.Volume = volume; mp.Play(); The problem arises because this is part of a Prism module. I don't know where the executing assembly is going to be so I can't use a relative Uri or siteoforigin and MediaPlayer doesn't understand the pack Uri syntax. I have a resource wav file at the root of my assembly called "notify.wav", but I have no way to pass it

Connect pipes of processes in php

隐身守侯 提交于 2019-12-22 12:19:57
问题 I would like the output of one process created with proc_open to be piped to another one created with proc_open (in php). For example. In bash I can do: [herbert@thdev1 ~]$ cat foo 2 3 1 [herbert@thdev1 ~]$ cat foo | sort 1 2 3 [herbert@thdev1 ~]$ I would like to simulate this in php using proc_open (instead of shell_exec) in order to have control over return-codes, pipes, etc. So I want something like this: $catPipes=array(); $sortPipes=array(); $cwd = '/tmp'; $env = array(); $catProcess =
