Akira AJISAKA created HDFS-6682: ----------------------------------- Summary: Add a metric to expose the timestamp of the oldest under-replicated block Key: HDFS-6682 URL: https://issues.apache.org/jira/browse/HDFS-6682 Project: Hadoop HDFS Issue Type: Improvement Reporter: Akira AJISAKA Assignee: Akira AJISAKA
In the following case, the data in the HDFS is lost and a client needs to put the same file again. # A Client puts a file to HDFS # A DataNode crashes before replicating a block of the file to other DataNodes I propose a metric to expose the timestamp of the oldest under-replicated/corrupt block. That way client can know what file to retain for the re-try. -- This message was sent by Atlassian JIRA (v6.2#6252)
