----------------------------
Summary: TezMerger should sort FileChunks on decompressed size
Key: TEZ-1733
URL: https://issues.apache.org/jira/browse/TEZ-1733
Project: Apache Tez
Issue Type: Bug
Affects Versions: 0.5.2
Reporter: Gopal V
MAPREDUCE-3685 fixed the Merger sort order for file chunks to use the
decompressed size, to cut-down on CPU and IO costs.
TezMerger needs an equivalent sorted TreeSet which sorts by the data with-in
sizes rather than actual file sizes.
