> Key: ARROW-61
> URL: https://issues.apache.org/jira/browse/ARROW-61
> Project: Apache Arrow
> Issue Type: Bug
> Components: Java - Vectors
> Environment: Apache Drill, Apache Arrow
> Reporter: Vitalii Diravka
> Labels: adjustScale, arrow, decimal
>
> Method org.apache.drill.exec.util.DecimalUtility.adjustScaleMultiply(long
> input, int factor) can return the value bigger than long max value.
> For example by comparison two decimal18 values 9223372036854775807 and 0.001.
> To adjust first value scale this method should return 9223372036854775807 *
> 1000 - bigger than long max value.
> Class DecimalUtility.java will be a part of org.apache.arrow after renaming
