hyphen in hive struct field

[Udit Mehta <um...@groupon.com>]

Hi,

I have a hive table query:

create external table test (field1 struct< `inner-table` : string>);

I believe hyphens are disallowed  but to overcome that i read that we can
use ``(ticks) around them. But even this seems to fail.

Is there a way around this or hypens are not allowed in nested hive tables?

Thanks,
Udit
