> In Pig 0.8 , the stats is showing wrong information when ever I have multiple loads and the the file names are similar .
> a) Problem 1
> Sample Script : 
> A = LOAD 'myfolder/tryme' AS (f1);
> B = LOAD 'myfolder/anotherfolder/tryme' AS (f2);
> C = JOIN A BY f1, B BY f2;
> DUMP C;
> Here I have 10 records for A and 3 records for B , but pig says 
> Successfully read 6 records from: "<nn>/myfolder/anotherfolder/tryme"
> Successfully read 6 records from: "<nn>myfolder/tryme"
> b) Problem 2
> A = LOAD 'myfolder/tryme' AS (f1);
> B = LOAD 'myfolder/an1111otherfolder/tryme' AS (f2);
> C = JOIN A BY f1, B BY f2;
> DUMP C;
> Here there is no folder named an1111otherfolder while "myfolder/tryme" exists . But pig says
> Failed to read data from "<nn>/myfolder/an1111otherfolder/tryme"
> Failed to read data from "<nn>/myfolder/tryme"
