URL: https://github.com/apache/carbondata/pull/3940
### Why is this PR needed?
Reading negative decimal numbers gives the wrong value from presto.
### What changes were proposed in this PR?
When complex decimal column is stored with DIRECT_COMPRESS codec,
DataTypeUtil#bigDecimalToByte is used to create a byte array. So, while
decoding it, need to use DataTypeUtil#byteToBigDecimal to get back the proper
value.
Originally added a TODO to find what is happening at write step for decimal,
handled as part of this issue.
### Does this PR introduce any user interface change?
- No
### Is any new testcase added?
- Yes
