I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/21533
to look at the new patch set (#2).
Change subject: IMPALA-13166: Optimize ExprSubstitutionMap allocation
......................................................................
IMPALA-13166: Optimize ExprSubstitutionMap allocation
Allocates HashMap and Lists with known sizes to avoid resizing them
during initial construction. HashMap uses default capacity of 16 and
load factor of .75, and we increase initial capacity as needed.
Has no measurable impact on performance, but may help with garbage
collection.
