Daryn Sharp commented on HDFS-12345:
------------------------------------
I like the concept of Dynamometer but I don't have cycles to review. I do have
general concerns about whether it should be part of the already bloated hadoop
project proper, or more importantly how we plan to maintain it going forward?
How much of a burden might it place on the community to support a non-essential
tool?
A cursory skim of comments seem to indicate use of private apis which gives me
pause. How extensive are the use of private apis? Essentially my concern is
if the tool will place a heavy burden on developers that change private hdfs
internals, only to find it's incompatible with the tool, lack the expertise to
"fix" the tool and spend substantial time attempting to fix it, or worse,
compromising a design change to accommodate a tool using private apis...

> Dynamometer has now been open sourced on our [GitHub
> page|https://github.com/linkedin/dynamometer]. Read more at our [recent blog
> post|https://engineering.linkedin.com/blog/2018/02/dynamometer--scale-testing-hdfs-on-minimal-hardware-with-maximum].
> To encourage getting the tool into the open for others to use as quickly as
> possible, we went through our standard open sourcing process of releasing on
> GitHub. However we are interested in the possibility of donating this to
> Apache as part of Hadoop itself and would appreciate feedback on whether or
> not this is something that would be supported by the community.
