Description

We have a schema that has a array<double> in it. We were unable to read this file and digging into ORC it seems that the issue is when the array is empty.

Here is the stack trace

If you create a ORC file with one row as the following

orc.addRow(Lists.newArrayList());

then try to read it

VectorizedRowBatch batch = reader.getSchema().createRowBatch();
while (rows.nextBatch(batch)) { }

You will produce the above stack trace.
