Subject [jira] [Updated] (HDFS-8425) [umbrella] Performance tuning and bug fixing for system tests for EC feature
Date Tue, 02 Jun 2015 03:41:18 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8425?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Walter Su updated HDFS-8425:
----------------------------
    Attachment: testClientWriteReadFile_v1.pdf

According to testClientWriteReadFile-v1.pdf, the reason for write performance degradation
is encoding, not networking. I'll add more test when native coders (HADOOP-11540) is available.
