-------------------------------------------

precision)
> Include scale and precision in error message when scale > precision
> -------------------------------------------------------------------

> Key: PARQUET-2452
> URL: https://issues.apache.org/jira/browse/PARQUET-2452
> Project: Parquet
> Issue Type: Improvement
> Reporter: Elliotte Rusty Harold
> Priority: Minor
>
> In Types.java we find this block of code:
> {code:java}
> Preconditions.checkArgument(precision > 0,
> "Invalid DECIMAL precision: %s", precision);
> Preconditions.checkArgument(this.scale >= 0,
> "Invalid DECIMAL scale: %s", this.scale);
> Preconditions.checkArgument(this.scale <= precision,
> "Invalid DECIMAL scale: cannot be greater than precision");
> {code}
> My program tripped the third precondition and it was harder to debug than it
> should have been because the scale and precision that violated the rule were
> not shown. Include both of these as in the previous two messages.
