Rohini Palaniswamy commented on PIG-3168:
-----------------------------------------
bq. PIG-2994 made explain with no alias be equivalent to explain on the
previous alias.
Shouldn't we revert back the behavior of explain with no alias to older
behavior of explaining the whole script instead of fixing the test? It is kind
of breaking backward compatibility.
> TestMultiQueryBasic.testMultiQueryWithSplitInMapAndMultiMerge fails in trunk

> PIG-2994 made explain with no alias be equivalent to explain on the previous

> TestMultiQueryBasic.testMultiQueryWithSplitInMapAndMultiMerge because the

> The following fixes the test:
> {code}
> "I = GROUP F2 BY (f7, f8);" +
> "STORE I into 'foo4' using BinStorage();" +
> - "explain;";
> + "explain I;";
> {code}
