Todd Lipcon commented on IMPALA-8533:
-------------------------------------
The problem here seems to be that the sorter is getting optimized to have a
zero-length sort tuple, so we crash on:
{code}
110 Sorter::Run::Run(Sorter* parent, TupleDescriptor* sort_tuple_desc, bool
initial_run)
111 : sorter_(parent),
112 sort_tuple_desc_(sort_tuple_desc),
113 sort_tuple_size_(sort_tuple_desc->byte_size()),
114 page_capacity_(parent->page_len_ / sort_tuple_size_),
{code}
(sort_tuple_size_ is 0, so we div-by-zero)
> Impala daemon crash on sort
