Subject Basic Hadoop Doubt
Date Mon, 17 May 2010 11:17:52 GMT

Hi All,

Vamc here, Buddy in Hadoop 

I have some basic doubt on hadoop Input Data placement...

Like, If i input some 30GB of data to hadoop program , it will place the
30gb into HDFS  into some set of files based on some input formats..

I have 2 doubts here ..

1. Each time i run a program 30GB is placed into HDFS or how its going to
Work 
2. Again if i want to run some other program on another 100Gb of data, where
the above stated data and program is different. Then the previous 30GB is
erased in HDFS or how its going to run..


please respond .

 Thanks  In Advance 

   vamsi
