Subject Re: [VOTE] Release Apache Hadoop 2.7.4 (RC0)
Date Fri, 04 Aug 2017 20:42:41 GMT
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?
