Koji Noguchi updated PIG-4841:
------------------------------
Attachment: pig-4841-v01.patch
In the patch I have two new tests, one from the description and another that I
decided not to fix as part of this jira and commented it out.
{code}
+ @Test
+ public void testWithInlineOpWithNestedForeach() throws Throwable {
+ // This one currently fails because "{}" is treated as
+ // IN_BLOCK in PigScriptParser.jj which jumps to PIG_END and ignore
+ // ") generate *; " part of the code.
+ // In order to support this test, we need to add parenthesis matching
+ // everywhere in PigScriptParser.jj (or stop using it)
+ //
+ String query = "a = load 'i1' as (f1:chararray);" +
+ "b = group a ALL; " +
+ "c = foreach ( foreach b {b1 = limit a 3; generate 1, b1;} )
generate *; " +
+ "dump c;";
+ ArrayList<String> msgs = new ArrayList<String>(); //
+ validate(query, true, msgs.toArray(new String[0]));
+ }
{code}
I had a patch that would cover this test case but it required me to add
parenthesis checking everywhere and it still gave me 10-20 more test failures
with mismatching ")". At that point, decided to step back and fix the original
case only and defer inlineop+nested-foreach case to PIG-2597 where we're trying
to move Grunt from javacc to ANTLR.
