Andrew Olson updated HADOOP-16294:
----------------------------------
Description:
In the DistCp class, the context is private with no getter method allowing
retrieval by subclasses. So a subclass would need to save its own copy of the
inputOptions supplied to its constructor and reconstruct the context if it
wishes to override the createInputFileListing method with logic similar to the
original implementation, i.e. calling CopyListing#buildListing with a path and
context.
I propose adding to DistCp this method,
{noformat}
protected DistCpContext getContext() {
return context;
}
{noformat}
