IMPALA-5031: memcpy requires two non-null arguments
Counterintuitively, even passing 0 as the third argument of memcpy
does not avoid undefined behavior. This occurred during an end-to-end
test. The interesting part of the backtrace is:
util/dict-encoding.h:451:20: runtime error: null pointer passed
as argument 2, which is declared to never be null
/usr/include/string.h:43:45: note: nonnull attribute specified
here
#0 DictEncoder<StringValue>::AddToTable(StringValue const&,
unsigned short*) util/dict-encoding.h:451:3
#1 DictEncoder<StringValue>::Put(StringValue const&)
util/dict-encoding.h:422:10
#2 HdfsParquetTableWriter::ColumnWriter<StringValue>::
ProcessValue(void*, long*)

#4 HdfsParquetTableWriter::AppendRows(RowBatch*,
vector<int> const&, bool*)
