Thanks -- it does appear that I misdiagnosed a bit: case works generally
but it doesn't seem to like the bit operation, which does not seem to work
(type of bit_field in Hive is bigint):
Error: java.lang.RuntimeException:
Unsupported language features in query: select (case when bit_field &
1=1 then r_end - r_start else NULL end) from mytable where
pkey='0178-2014-07' LIMIT 2

similarly, concat seems to work but I get a failure in this query (due to
LPAD I believe) :
select customer_id from mytable where
pkey=concat_ws('-',LPAD('077',4,'0'),'2014-07') LIMIT 2
(there is something going on with the fact that the function is in the
where clause....the following work fine:
select concat_ws('-', LPAD(cast(112717 % 1024 AS STRING),4,'0'),'2014-07')
from mytable where pkey='0077-2014-07' LIMIT 2 select customer_id from
mytable where pkey=concat_ws('-','0077','2014-07') LIMIT 2
)

Let me know if any of these warrant a JIRA
