[TRAFODION-2170] create table failure when pk length is too long
If the length of the primary key greater than 2048, Trafodion will have
memory overrun issue and core dump.
The changed method will alloc a 2048 buffer and do java memory copy later
into this buffer, which cause memory overrun.
This is rare, but still need to be fixed.
