Daniel Dai commented on PIG-613: -------------------------------- Here is another example: 1.txt: (0.2,0.3) a = load '1.txt'; b = foreach a generate (tuple(int, int))$0; describe b; b: {(int,int)} dump b; ((0.2,0.3)) The expect result is ((0, 0)) > Casting elements inside a tuple does not take effect > ---------------------------------------------------- > > Key: PIG-613 > URL: https://issues.apache.org/jira/browse/PIG-613 > Project: Pig > Issue Type: Bug > Components: impl > Affects Versions: 0.2.0 > Reporter: Viraj Bhat > Attachments: myfloatdata.txt, SQUARE.java > > > Consider the following Pig script which casts return values of the SQUARE UDF > which are tuples of doubles to long. The describe output of B shows it is > long, however the result is still double. > {code} > register statistics.jar; > A = load 'myfloatdata.txt' using PigStorage() as (doublecol:double); > B = foreach A generate (tuple(long))statistics.SQUARE(doublecol) as > squares:(loadtimesq); > describe B; > explain B; > dump B; > {code} > =========================================== > Describe output of B: > B: {squares: (loadtimesq: long)} > =========================================================== > Sample output of B: > ((7885.44)) > ((792098.2200010001)) > ((1497360.9268889998)) > ((50023.7956)) > ((0.972196)) > ((0.30980356)) > ((9.9760144E-7)) > =========================================================== > Cause: The cast for Tuples has not been implemented in POCast.java -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
