Raghotham Murthy updated HIVE-150:
----------------------------------
Attachment: hive-150.1.patch
Hi YihueyChyi,
There is an issue with service/build.xml. It currently assumes that you have
thrift installed. I am attaching the diff which will allow the build to proceed
even if you dont have thrift (this is ok since we are checking in the thrift
generated code as well). Please apply this patch (by running patch -p0 <
hive-150.1.patch in the hive top level directory.
> group by count(1) will get error
