Subject [jira] [Updated] (HDFS-7687) Change fsck to support EC files
Date Thu, 30 Apr 2015 11:02:08 GMT

     [ https://issues.apache.org/jira/browse/HDFS-7687?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Takanobu Asanuma updated HDFS-7687:
    Attachment: HDFS-7687.1.patch

I created an initial patch. The main codes in this patch are below.

# I separated {{collect\[File|Block\]Summary}} into {{collectReplicated\[File|Block\]Summary}}
and {{collectEC\[File|Block\]Summary}}.
# I named or renamed some variables and outputs. For example, {{ReplicatedBlocks}} is {{ECBlockGroups}}
in EC. And {{Replication}} or {{Replicas}} is {{ECBlocks}} in EC.
# I added EC summaries to Result#toString.

Please will you review this patch? I'm going to add some tests about this codes.

> We need to change fsck so that it can detect "under replicated" and corrupted EC files.
