Forgot to mention, also did Namenode performance testing using Dynamometer (see
http://mail-archives.apache.org/mod_mbox/hadoop-common-dev/201707.mbox/%3CCAGkyFnM7Ltpb-C_rxP43VUguRXb1bvxPH7GMqdSweE2iJx7i%2Bg%40mail.gmail.com%3E).
Reran production traces from multi-thousand node clusters and did not see any
noticeable performance regressions as compared to previous releases.

Hi,
I'm sorry coming to this vote late.
Daryn mentioned in HDFS-12136
<https://issues.apache.org/jira/browse/HDFS-12136> that HDFS-11160
<https://issues.apache.org/jira/browse/HDFS-11160> has a performance
regression at DataNode due to the way it locks dataset lock.
HDFS-11160 is in Hadoop 2.7.4. Would it be critical enough to warrant a
stop for release?
I myself can't reproduce the performance regression (assuming it only
occurs under extreme workload). Would Daryn or other Yahoo folks
comment?
