IMPALA-10703: Fix crash on reading ACID table while printing SchemaPath of
tuple/slots.
While reading ACID ORC file, the SchemaPath from TupleDescriptor
or SlotDescriptor are converted to fully qualified path via
PrintPath on few codepaths. PrintPath needs non-canonical table
path though. For non-ACID table this will be same as SchemaPath
of tuple/slot. However for ACID tables, it will be different as
file schema and table schema are not same.
E.g., ACID table foo(id int) will look like following in file:
{
operation: int,
originalTransaction: bigInt,
bucket: int,
rowId: bigInt,
currentTransaction: bigInt,
row: struct<id: int>
}
So SchemaPath for id will [5, 0], but PrintPath would not
understand that. It needs to be converted into table path [1]
as table schema looks like this:
{
row_id: struct < ...ACID Columns>
id: int
}
