> In FRJoin, if input path has curly braces, it fails to compute number of
> input files and logs the following exception in the log -
> 10/09/27 14:31:13 WARN mapReduceLayer.MRCompiler: failed to get number of
> input files

> This does not cause a query to fail. But since the number of input files
> don't get calculated, the optimizations added in PIG-1458 to reduce load on
> name node will not get used.
