Jason Lowe updated YARN-5483:
-----------------------------
Affects Version/s: 2.6.0
Target Version/s: 2.6.5, 2.7.4
bq. I don't think YARN-5262 breaks this jira.
Yeah, it looks like YARN-1372 is the source, and that went into 2.6. As such
it'd be nice to have this go into 2.7.4 and 2.6.5 since it seems like an
important performance fix.
Thanks for updating the patch! Latest one looks good to me as well. Could you
provide patches for 2.7/2.6 as well? Note that 2.6 does not support JDK7, so
we can't use the diamond operator there.
