what's easiest way find file associated block in hdfs given block name/id the long , painful way, assuming have read access files (and execute directories): hadoop fsck / -files -blocks | grep blk_520275863902385418_1002 -b 20 then scan block match previous file name: /hadoop/mapred/system/jobtracker.info 4 bytes, 1 block(s): ok 0. blk_520275863902385418_1002 len=4 repl=1 in case blk_5202... part of /hadoop/mapred/system/jobtracker.info file programmatically, these isn't interface name node allows search block id, source secondary name node , see how consolidates edits - experiment on saved output secondary name node (rather risking working on live name node file). good luck!

i'm new c++, , i'm familiar java. first thing wondering when started looking @ c++ code classes (not members) don't have access specifiers such private , protected , public . exemples here , here . public class { // line. private class b { } // not line. } why so? there's no access modifier @ level of classes, since language has no concept of package . there @ level of data members, member functions , inheritence: class foo {}; class bar : public foo { public: void bar() const {} private: int bar_(float) {} int a, b, c; }; the closest can declaring nested classes inside class: class foo { struct bar0 { void bar0() const {} }; struct bar1 { bar0 b0; bar1() { b0.bar0();} }; };

i have 2 series of values. showing them in chart, quite similar (they have same behavior, when 1 grows, other 1 grows, when 1 has small values, other has small values; but: may occur 1 growing , other descending). important not have strictly same values. interested in general behavior of these 2 charts. right now, comparing them doing average on both graphs, , building 2 bool arrays. when value above average, corresponding value in bool[] true, otherwise false. compare these 2 bool[], using hamming distance. algorithm works, not wished work. (it doesn't detect matches between charts). does have idea of better algorithm performing operation? thank you. a simple way of calculating distance between 2 lists of numbers calculate sum of squares of differences between them. used quite in statistics. double sum = 0.0; (int = 0; < n; i++) { double diff = a[i] - b[i]; sum += diff*diff; } but fundamental question is, kind of statement expecting such analysis....

i have webview pdf file , document in contains hyperlinks want disable. tried using approach didn't work, links still open , load nasty urls: i put uiwebviewdelegate in viewcontroller.h i put code in viewcontroller.m : - (bool)webview:(uiwebview *)webview shouldstartloadwithrequest:(nsurlrequest *)request navigationtype:(uiwebviewnavigationtype)navigationtype { if (webview == myreadingarticleswebview) { return no; } else { return yes; } } any ideas how make simple , easy work? admit make mistakes in process described above. edit: - (bool)webview:(uiwebview *)webview shouldstartloadwithrequest:(nsurlrequest *)request navigationtype:(uiwebviewnavigationtype)navigationtype { if ([request.url isfilereferenceurl]) { return yes; } else { return no; } } the code above nothing me well if trumpetlicks says pdf viewer ignores shouldstartloadwithrequest, , if don't want disable links (which...

my question pretty explained in title. how html tags inside of javascript text node? result of code on page is... <a href="http://www.example.com">click here</a> however, want "click here" link. new javascript, me out lot. below example of i'm talking about... <div id="mydiv"> </div> <script type="text/javascript"> var mynode=document.createtextnode('<a href="http://www.example.com">click here</a>'); document.getelementbyid('mydiv').appendchild(mynode); </script> you can't put links in text node. links elements. elements can (sometimes) contain text nodes, reverse not true. you need create element, set attributes on it, append text element. var link = document.createelement('a'); link.setattribute('href', 'http://www.example.com'); link.appendchild(document.createtextnode('click here')); document.getelementbyid(...

i can create pushbutton filesavedialog1.dialog.queryinterface shown below. how setup , handle onpushbutton click event can respond button click? procedure tform1.filesavedialog1execute(sender: tobject); const dwvisualgroup1id: dword = 1900; var c: ifiledialogcustomize; d: ifiledialogcontrolevents; begin if filesavedialog1.dialog.queryinterface(ifiledialogcustomize, c) = s_ok begin // add advanced button c.addpushbutton(dwvisualgroup1id, 'advanced'); c.makeprominent(dwvisualgroup1id); // setup pushbutton click event? end; the following works fine me in xe2: type tmyfiledialogevents = class(tinterfacedobject, ifiledialogevents, ifiledialogcontrolevents) public { ifiledialogevents } function onfileok(const pfd: ifiledialog): hresult; stdcall; function onfolderchanging(const pfd: ifiledialog; const psifolder: ishellitem): hresult; stdcall; function onfolderchange(const pfd: ifiledialog): hresult; stdcall; ...

is there methodology -- , if so, -- finding out exceptions may thrown particular statement? e.g., given following code: string substr = selectedfilename.substring(date_begin_pos, date_length); return datetime.parse(substr); ...how know exception[s] might thrown second line? think 1 highlight line, , select context menu supply this/these... as far i'm aware there isn't way of finding out other looking on msdn: http://msdn.microsoft.com/en-us/library/1k1skd40.aspx the easy/lazy/c# way of doing "catch (exception e)" , deal generic exception type. have of information need in type exceptions anyway. exception handling should used logging/promoting, imho knowing datetime.parse can throw either formatexception or arguementnullexception pointless (to me).

if birthdate's stored type "date" in mysql, how determine if it's specific user's birthday today in php? is matter of grabbing birthdate column value, doing on explode on - , , checking if day , month match current day , month in php? or there simpler , less crude way of doing it? also, query use select all users birthday today? since you'll need exclude year, can use month , day sql functions so: select * table month(birthday) = month(now()) , day(birthday) = day(now()); don't forget add index on column or degrade performance data grows. in php, can use date function: if (date('m-d', strtotime($row['date'])) == date('m-d')) //-- today birthday! hooray!
