Mike George created HDFS-6074: --------------------------------- Summary: Under replicated blocks with ONE replica should get replication priority over blocks with more than one replica. Key: HDFS-6074 URL: https://issues.apache.org/jira/browse/HDFS-6074 Project: Hadoop HDFS Issue Type: Improvement Components: namenode Affects Versions: 2.2.0 Reporter: Mike George Priority: Minor
We had two nodes fail at the same time. There were over 2000 blocks at higher risk of causing corrupt files since they were single replica. There were over 40000 under replicated blocks with most having two replicas and the namenode priority to recreate missing replicas clearly placed no priority of single replica blocks. -- This message was sent by Atlassian JIRA (v6.2#6252)
