Zesheng Wu created HDFS-4916: -------------------------------- Summary: DataTransfer may mask the IOException during block transfering Key: HDFS-4916 URL: https://issues.apache.org/jira/browse/HDFS-4916 Project: Hadoop HDFS Issue Type: Bug Components: datanode Affects Versions: 2.0.4-alpha Reporter: Zesheng Wu Priority: Blocker
When a new datanode is added to the pipeline, the client will trigger the block transfer process. In the current implementation, the src datanode calls the run() method of the DataTransfer to transfer the block, this method will mask the IOExceptions during the transfering, and will make the client not realize the failure during the transfering. -- This message is automatically generated by JIRA.
