Nathan Roberts created HDFS-8404: ------------------------------------ Summary: pending block replication can get stuck using older genstamp Key: HDFS-8404 URL: https://issues.apache.org/jira/browse/HDFS-8404 Project: Hadoop HDFS Issue Type: Bug Components: namenode Affects Versions: 2.7.0, 2.6.0 Reporter: Nathan Roberts Assignee: Nathan Roberts
If an under-replicated block gets into the pending-replication list, but later the genstamp of that block ends up being newer than the one originally submitted for replication, the block will fail replication until the NN is restarted. It will be safer if processPendingReplications() gets up-to-date blockinfo before resubmitting replication work. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
