Venki Korukanti created ARROW-2368:
--------------------------------------
Summary: DecimalVector#setBigEndian is not padding correctly for
negative values
Key: ARROW-2368
URL: https://issues.apache.org/jira/browse/ARROW-2368
Project: Apache Arrow
Issue Type: Bug
Components: Java - Vectors
Reporter: Venki Korukanti
Assignee: Venki Korukanti
If the input given is less than 16 bytes, we pad zero for the remaining bytes
[1]. This is not correct if the value is a negative number. We should pad 0x00
or 0xFF depending upon the number is a positive or negative number. Later when
the value is retrieved we end up with an incorrect value.
