Commit 8e4b32db984945ca82a7d6c931b2316aee2c385c in impala's branch refs/heads/master from Michael Smith
[ https://gitbox.apache.org/repos/asf?p=impala.git;h=8e4b32db9 ]
IMPALA-11917: Drop redundant const from Codec::CodecMap
The map's value_type already makes the key const, and a const mapped
type is not needed, so use std::map<std::string, THdfsCompression::type>
and update the matching iterator type in HdfsScanner.
