Subject [jira] [Commented] (HDFS-2149) Move EditLogOp serialisation and deserialation into one place
Date Thu, 14 Jul 2011 18:10:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2149?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13065429#comment-13065429

Aaron T. Myers commented on HDFS-2149:

I also find the OEV code confusing. I think its implementation of the visitor pattern is slightly
different from what is usually done.

As for a benchmark, I'd recommend either using {{NNThroughputBenchmark}} or writing your own
custom micro-benchmark in the same vain as HDFS-1846.
