Yiqun Zhang created ORC-1082:
--------------------------------
Summary: 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: Bug
Components: Java, tools
Affects Versions: 1.7.2, 1.6.12
Reporter: Yiqun Zhang
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}
