-------------------------------------------
Summary: DistCp diff option support for snapshot root descendant
directories
Key: HADOOP-14983
URL: https://issues.apache.org/jira/browse/HADOOP-14983
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 3.0.0
Reporter: Manoj Govindassamy
Assignee: Manoj Govindassamy
HDFS-12544 enables SnapshotDiff generation on any snapshot root descendant
directory. Previous to this, all snapshot diff operations had to be based on
snapshot root directory. DistCp already supports update diff option by which
snapshot diff report between any given two snapshots can be used to identify
the difference between source and target, and apply the diff to the target to
make it in sync with source. But, the snapshot source and target paths need to
be a snapshot root directory for the diff option to work.

DistCp -update -diff <oldSnapshot> <newSnapshot> <source-snapshot-root-dir>
<target-snapshot-root-dir>
{noformat}
Better if DistCp can also support update diff option on any descendant
directories under snapshot root, provided HDFS-12544 is enabled.
