Jenny Thompson created PIG-3805:
-----------------------------------
Summary: ToString(datetime [, format string]) doesn't work without
the second argument
Key: PIG-3805
URL: https://issues.apache.org/jira/browse/PIG-3805
Project: Pig
Issue Type: Bug
Components: internal-udfs
Affects Versions: 0.12.0
Reporter: Jenny Thompson
Priority: Minor
The exec function of ToString is written to handle a 1 or 2 arguments (it
defaults to ISO, which is consistent with ToDate).
However, the getArgToFuncMapping function returns only one FuncSpec, requiring
the formatString argument.
To fix: just return add another FuncSpec to getArcToFuncMapping.
