Subject [jira] [Updated] (HDFS-7166) SbNN Web UI shows #Under replicated blocks and #pending deletion blocks
Date Fri, 04 Mar 2016 16:23:40 GMT

     [ https://issues.apache.org/jira/browse/HDFS-7166?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Wei-Chiu Chuang updated HDFS-7166:
    Attachment: HDFS-7166.001.patch

SbNN will not show corrupted blocks, under-replicated blocks, missing block. In addition,
it should also not show blocks that are pending deletion, according to {{TestStandbyBlockManagement}}.

I tested this patch on a CDH cluster with HA and works as expected.
