Subject fails to alter table concatenate
Date Tue, 30 Jun 2015 08:16:59 GMT
Hi,

I am using hive 0.14. It fails to alter table concatenate occasionally 
(see the exception below). It is strange that it fails from time to time 
not predictable. Is there any suggestion/clue?

hive> alter table 4dim partition(zone=2,z=15,year=2005,month=4) CONCATENATE;
