Subject [jira] [Updated] (HADOOP-11588) Benchmark framework and test for erasure coders
Date Tue, 09 Aug 2016 05:47:20 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-11588?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Rui Li updated HADOOP-11588:
    Attachment: HADOOP-11588.7.patch

Thanks Kai. The v6 patch generates a warning (convertToByteBufferState is invoked) when testing
ISA-L coder. That's when we initializing the coder and it doesn't affect the performance result.
Upload v7 patch to avoid it, and also adds the missing JavaDoc.

and test to help evaluate which one outperforms in certain environment. This is to implement
the benchmark framework.
