Allen Wittenauer commented on HADOOP-10949:
-------------------------------------------
hadoop-tools still suffers from the same sorts of problems though, just on a
smaller scale, made worse by how it is laid out vs. the rest of Hadoop. To be
more specific, most of the sub-projects do:
{code}
share/hadoop/(project) <- hadoop bits
share/hadoop/(project) <- dependencies
{code}
tools, on the other hand, just does share/hadoop/tools/lib, with both the
hadoop bits and the dependencies intermingled. Every time someone issues a
command that needs tools support (e.g., distcp), all of this stuff gets pulled
in. This is a historical issue, and probably one that should get broken in 3.x.
If we move all of the metrics sinks so their own universe, the file layout
should be changed appropriately.
