i'm newbie in hdfs, sorry if question naive. suppose store files in hadoop cluster. files popular , requested often(but not put them in memory) other. worth keep more copies(replicas) of files. can implement in hdfs or there best practice tackle task? yes, can entire cluster/directory/file individually. you can change replication factor(lets 3) on per-file basis using hadoop fs shell. [sys@localhost ~]$ hadoop fs –setrep –w 3 /my/file alternatively, can change replication factor(lets 3) of files under directory. [sys@localhost ~]$ hadoop fs –setrep –w 3 -r /my/dir to change replication of entire hdfs 1: [sys@localhost ~]$ hadoop fs -setrep -w 1 -r / but replication factor should lie between dfs.replication.max , dfs.replication.min value.

what best way create multiple android apps in 1 xamarin form solution? i've tryed add new android project solution, updated references, packages , mainactivity.cs build in .android project when try run project system.nullreferenceexeption in loadappliction(new app()); function i should suggest unload other projects while testing one. example wrote preprocessor directives handle platform specific codes on shared codes like #if __ios__ bla bla #endif #if __android__ bla bla #endif but setup ios project start project, visual studio did not see ios symbol; defined on ios project properties! did unload android project , went well. unload ios project , load android , android project gone too. i'm not sure case can give try :)

i in progress of making angularjs app c# web api. i have controller , b. in controller a, have list of objects, when click add (between 2 list items), controller b. //add item $location.path("/controllerb") inside controller b prestented list of objects, when select, need selected item, appear in controller a's list, @ sepcified index. my approach far: localstorage: use localstorage store selected object, accessible controller a, need index, , if store in ls access controller b, im headed down path of bad decisions feel :d so best guess far: 1. save index controller in local storage. (go b) 2. save selecteditem controller b in local storage. (go a) 3. push selecteditem index. so please, point me in angular direction. consider using angular service hold data, inject service in controller , controller b. have @ topic: what's correct way communicate between controllers in angularjs?

the essence of question is: possible use wamp notifications in django application supporting both python 2.7 , 3.4, considering code should running , interrupted if remote procedure call made? (that is, it's not waiting rpc come) how want use wamp: program has javascript frontend python/django backend. 1 of things start function in backend when button in frontend clicked. takes time though, allow user cancel clicking button. 1 makes remote procedure call, cause function stop earlier (it changes variable checked in function). there might other needs rpc or pub/sub in future too. we got working python 2.7 using autobahn_sync module, uses twisted, hasn't yet been ported python 3.x. that's why need way of getting our wamp notification work on 3.x. asyncio supported , crossbar documentation seemed used instead of twisted, can't work without blocking code should running in parallel (code added below). , there doesn't seem autobahn_sync using asyncio instead o

i'm working on project in codeigniter follows mvc pattern, i've created model send verification email website's signed members. code working using google's smtp on localhost site live , don't know protocols , web-mail, i'm new this.. localhost code here: $config = array( 'protocol' => 'smtp', 'smtp_host' => 'ssl://smtp.googlemail.com', 'smtp_port' => 465, 'smtp_user' => 'my mail', 'smtp_pass' => 'my password', 'mailtype' => 'html', 'charset' => 'iso-8859-1', 'wordwrap' => true ); now changes needed use through web mail cpanel?? in webmail settings find smtp settings. ports same in major case. need change host, username , password per new server. there link "configure mail client" in email secti

i have class which, interface-wise, simple this: struct foo { inline foo & operator << (int i) { return *this; } }; i can use in following way: foo foo; foo << 1 << 2 << 3 << 4; now restrict usage of operator. for instance , called number of times between sequence points. i address problem using internal proxy class. temporary created which, @ end of control sequence, destroyed , checks how many times operator has been called: struct foo { inline foo() : m_count(0) {} private: struct fooproxy { friend struct foo; inline ~fooproxy(); inline struct foo & operator << (int i); private: inline fooproxy(struct foo &foo) : m_foo(foo) {} struct foo &m_foo; }; public: inline fooproxy operator << (int i); private: int m_count; }; inline foo::fooproxy foo::operator << (int i) { ++m_count; return fooproxy(*this); } in

this seems simple, reason using vaadin 7.0.7 , listselect seems marked dirty while obtaining data display. the code .... fieldgroup group = new fieldgroup(bean); sqlcontainer c = new sqlcontainer(new tablequery(null, "user", "system", pool, new oraclegenerator())); listselect options = new listselect("system", c); group.bind(options, "system"); .... but seems throwing error, when listselect obtaining ids, sql container seems marked dirty when there's update java.lang.illegalstateexception: connector should not marked dirty while response being written. @ com.vaadin.ui.connectortracker.markdirty(connectortracker.java:346) @ com.vaadin.server.abstractclientconnector.markasdirty(abstractclientconnector.java:139) @ com.vaadin.ui.abstractselect.fireitemsetchange(abstractselect.java:1679) @ com.vaadin.ui.abstractselect.containeritemsetchange(abstractselect.java:1646) @ com.vaadin.data.util.sqlcontainer.sqlcontainer.firecontentschange(sq

i have made heatmap represents value color intensity.how create heatmap in size of rectangles used represent value json? have tried following code not giving required output. <body> <div id="chart"></div> <div id="dataset-picker"> </div> <script type="text/javascript"> var width=400, height=300, buckets=9, colors = ["#ccd9ff", "#99b3ff", "#668cff", "#3366ff", "#0040ff", "#0033cc", "#002699", "#002080", "#00134d"], datasets = [{ "day": 1, "hour": 1, "value1":16, "value2":20 }, { "day": 1, "hour": 2, "value1":23, "value2":10

i have following table: rating -------- | id | account_id | room | kitchen | bathroom | ----------------------------------------------- | 1 | 1 | 5 | 5 | 5 | | 2 | 1 | 2 | 4 | 1 | | 3 | 1 | 5 | 2 | 1 | ----------------------------------------------- people can rate room, kitchen , bathroom (from 1-5). average rating id = 1: 5 (because 15/3 = 5) average rating id = 2: 2.3333 (because 7/3 = 2.33333) average rating id = 3: 2.6666 (because 8/3 = 2.66665) first question as can see, average rating id = 2 => 2.3333... , id = 3 => 2.6666. how can make floor() , ceil()? (when < .5 => floor, when > .5 => ceil), avg rating id = 2 becomes 2 (instead of 2.3333) , avg rating id = 3 becomes 3 (instead of 2.6666...) second question i want select average rating of average ratings (so average rating rows together). - when floor() , ceil() used have 3 average ratings: 5, 2 , 3 => 10/15

my webpack config compiles .scss files css in pretty standard way: { test: /\.scss$/, exclude: /(node_modules|bower_components)/, loaders: ['style', 'css', 'sass'] } what i'd do, though, have url , file loaders work inside *.scss files, end goal of inlining smaller images: &.backdrop { background-image: require('../../assets/images/backdrop-1.jpg'); } it seems webpack ignoring require() call, though, css results identical code above (i.e. browser told try , render background image found @ require('../../' [etc etc] . loader i've been trying above: { test: /\.jpg$/, loader: 'url', query: { limit: 250000 } } can suggest i'm going wrong?
