Trying to compile types branch to verify/check this problem.

I get the following compile error and have checked all the obvious
stuff:

$ ant compile
Buildfile: build.xml

This could be a bug. Can you try it with pig.jar build from type branch
and see if you get the expected results?

Note that type branch is still on Hadoop 17 but will move to Hadoop 18
later today.

Subject: DISTINCT Problem

Hi All,



I seem to be seeing a problem with the DISTINCT operator. I
have a script that looks like this:



raw_tran_hdr = load 'tran_hdr/tran_header' using PigStorage(
'|' ) as ( ... many fields ... );

tran_hdr_dist = DISTINCT raw_tran_hdr;

b = GROUP tran_hdr_dist ALL;

c = FOREACH b GENERATE COUNT(tran_hdr_dist.$0);



The data set 'tran_hdr/tran_header' has about 7M rows of
which I know for certain 14 are exact duplicates. When I
execute the Pig script above I get the total row count; that
is, the number returned doesn't correctly drop out the duplicate rows.



There is a thread in the user group about previous DISTINCT
problems that sound just like this but JIRA says they're all
resolved. The code I'm using is up-to-date with the trunk (@
revision 698759) so I'm assuming I've picked up any fixes.



When (in a different script) I move the DISTINCT into a
nested FOREACH it fixes (or at least works-around) the problem; e.g.:



(after COGROUP)



Z = FOREACH X

{

thd = DISTINCT raw_tran_hdr;

GENERATE

FLATTEN( thd.(... many fields .... ) ),

FLATTEN( sale_line_calc.(... many fields ...) );

}



I will continue to try to dig into the problem but any
guidance anyone can provide would be appreciated. Maybe I'm
misunderstanding something.

As mentioned, I am successfully working around the issue
right now but - as a data junkie like I know you all are -
answers that look incorrect make me nervous.



BTW, I don't think this is just a counting issue with
DISTINCT (as the previous issues seem to allude to); when I
tried to use tran_hdr_dist to do a COGROUP (without counting)
I got wrong results.



Thanks,

PaulO.

    Hi Olga et al,

    I have made a little progress in figuring out what's going on for me
    with the types branch.

    When 'test\utils\dotGraph\parser\Dot.jj' is generated the first line of
    the generated file looks like this:

    /*@bgen(jjtree) Generated By:JJTree: Do not edit this line.
    C:\dev\pig\test\org\apache\pig\test\utils\dotGraph\parser\Dot.jj */
    /*@egen*/options {

    Long story short it chokes - believe it or not - on the '\u' of
    '...test\utils...' because it thinks it's a Unicode character. I
    believe this is a known issue with Java compilation and it explains why
    it seems to be a Windows-only problem.

    Don't know what the 'fix' is for this (other than getting off Windows)
    but I can work around the problem by whacking the JJ file directly.

    However, when I do this (on the types branch) I seem to see a problem
    where I can't execute any commands from the grunt shell. Every command
    fails immediately with a parse error:

    2008-10-06 17:51:31,421 [main] INFO
    org.apache.pig.backend.hadoop.executionengi
    ne.HExecutionEngine - Connecting to map-reduce job tracker at:
    localhost:9001
    grunt> ls
    org.apache.pig.tools.pigscript.parser.ParseException: Encountered "l" at
    line 1,
    column 1.
    Was expecting one of:
    <EOF>
    "cat" ...
    "cd" ...
    <snip>

    Don't know if this is related to the same issue above or caused by my
    having to whack the file or what...?

    Anyway, this all goes back to the DISTINCT problem I was seeing. I'd be
    happy to try to recreate the problem on the types branch if I can get it
    built or someone can provide me with a JAR to test with.

    Thanks,
    PaulO.

    first line of the generated file looks like this:

    /*@bgen(jjtree) Generated By:JJTree: Do not edit this line.
    C:\dev\pig\test\org\apache\pig\test\utils\dotGraph\parser\Dot.
    jj */ /*@egen*/options {

    Long story short it chokes - believe it or not - on the '\u'
    of '...test\utils...' because it thinks it's a Unicode
    character. I believe this is a known issue with Java
    compilation and it explains why it seems to be a Windows-only problem.

    Don't know what the 'fix' is for this (other than getting off
    Windows) but I can work around the problem by whacking the JJ
    file directly.

    However, when I do this (on the types branch) I seem to see a
    problem where I can't execute any commands from the grunt
    shell. Every command fails immediately with a parse error:

    2008-10-06 17:51:31,421 [main] INFO
    org.apache.pig.backend.hadoop.executionengi
    ne.HExecutionEngine - Connecting to map-reduce job tracker at:
    localhost:9001
    grunt> ls
    org.apache.pig.tools.pigscript.parser.ParseException:
    Encountered "l" at line 1, column 1.
    Was expecting one of:
    <EOF>
    "cat" ...
    "cd" ...
    <snip>

    Don't know if this is related to the same issue above or
    caused by my having to whack the file or what...?

    Anyway, this all goes back to the DISTINCT problem I was
    seeing. I'd be happy to try to recreate the problem on the
    types branch if I can get it built or someone can provide me
    with a JAR to test with.

    Thanks,
    PaulO.

    We are not seeing it on our builds but none of us run on
    Window. While we figure out what is going on, I can send you
    a jar file build from types branch. Are you running with
    Hadoop 17 or Hadoop 18 cluster?

    Yes. I cannot currently compile the 'types' branch.

    Is this repeatable?
