Dongjoon Hyun closed ORC-1082.
------------------------------
> FileDump and JsonFileDump do not correctly handle the case where the RowIndex
> does not have column statistics
> -------------------------------------------------------------------------------------------------------------
>
> Key: ORC-1082
> URL: https://issues.apache.org/jira/browse/ORC-1082
> Project: ORC
> Issue Type: Improvement
> Components: Java, tools
> Affects Versions: 1.8.0, 1.7.3
> Reporter: Yiqun Zhang
> Assignee: Yiqun Zhang
> Priority: Major
> Fix For: 1.7.3
>
>
> Before we can get the ColumnStatistics from RowIndex we need to determine
> whether it exists or not.
> entry.getStatistics(); does not return null at any time, and will return a
> default object when it is not set.
>
> {code:java}
> OrcProto.ColumnStatistics colStats = entry.getStatistics();
> if (colStats == null) {
> buf.append("no stats at ");
> }
> {code}
