Lisheng Sun updated HDFS-4916: ------------------------------ Resolution: Implemented Status: Resolved (was: Patch Available) > 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, 2.0.5-alpha > Reporter: Zesheng Wu > Assignee: Lisheng Sun > Priority: Critical > Labels: BB2015-05-TBR > Attachments: 4916.v0.patch > > > 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 transferring, as a result the client will > mistake the failing transferring as successful one. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
