Ted Yu updated CARBONDATA-2332:
-------------------------------
Description:
Here is one example from getFloatPage :
{code}
for (int i = 0; i < data.length; i++) {
long offset = i << floatBits;
{code}
The shift expression with type "int" (32 bits, signed) is evaluated using
32-bit arithmetic.
But the variable offset is of type long.
There are a few other shift expressions of this nature.
