Subject Re: HIVE ODBC test fails at testing with isql
Date Thu, 06 Jan 2011 18:08:22 GMT
I guess libodbc.so is the one you renamed from libodbchive.so? If so can you ldd libodbc.so
and see what other .so files are linked? You can follow the links and do the ldd check for
all necessary .so files (libodbchive.so, libhiveclient.so and libthrift.so). Also please make
sure all these .so files are compiled to compatible architecture (i.e., all 32-bit or 64-bit)
as mentioned in the Hive ODBC wiki.
