($title);
    print ''.$row_title['shop_feild'].'';
}

This function will tell website url eg ( http://google.com )
and i want to call this function in string concatenation 
echo '<script language="javascript">'.'window.location =
    "'.site_url().'";'.'</script>';

i also called function into variable! to testing but it's not work
$page = site_url();
echo '<script language="javascript">'.'window.location = "'.$page.'";'.'</script>';

so how can i call function when i want to string concatenation?

A:

You need to return the result of site_url rather than printing the text immediately.
function  site_url() {
    include("../connect.php");
    $title= mysql_query("select * from shop_option where shop_key='site_url' ");
    $row_title= mysql_fetch_array($title);
    return $row_title['shop_feild'];
}

 Q:

Number of Map Jobs created based on Data Volume

Whenever we run any Map job on any volume of Data, by default certain number of map jobs getting created. I wanted to know the logic behind it. 

Consider the situation when I am trying to upload data on HDFS or
  using sqoop to upload data to HIVE

Is there some static number of jobs based on volume of data like
Mathematical Formula.
Is there some intelligent system which understands your data based on
Supervised clustering algorithm and it group data in each of the Map?

I wanted to know exactly how Hadoop knows about number if Map jobs, I tried to find the answer in internet but I couldn't find the exact reply.

A:

The number of map tasks executed depends on the number of input splits calculated.
The logic to compute the number of input splits depends on the InputFormat used in the MapReduce job.
One map task will be spawned for each input split, so if there are 3 input splits we will have 3 map tasks
You can create a custom InputFormat if you need to customise this logic in anyway
Have a look at the Definitive Guide for more details

 Q:

Differential equation with $w$ and $
( $ title); 
     print" .$row_title['shop_feild' ].";

 This function will tell web site url eg (http://google.com) 
 and i desire to bid this function in string chain 
 echo' < script language="javascript">'.'window.location = 
     "' .site_url().'";'.'</script >'; 

 i also called affair into variable! to testing but it's not employment 
 $ page = site_url (); 
 echo' < script language="javascript">'.'window.location = "' .$page.'";'.'</script >'; 

 indeed how can i call function when i desire to string concatenation? 

 A: 

 You need to return the result of site_url rather than printing the textbook immediately. 
 function   site_url () { 
     include(".. /connect.php "); 
     $ title= mysql_query("select * from shop_option where shop_key='site_url' ");

 I wanted to know exactly how Hadoop knows about numeral if Map jobs, I tried to find the answer in internet but I couldn't rule the exact reply. 

 A: 

 The number of map tasks executed count on the number of input splits calculated. 
 The logic to calculate the number of input signal splits depends on the InputFormat used in the MapReduce job. 
 One map undertaking will be spawned for each input split, so if there be 3 input splits we will have 3 map job
