Kihwal Lee reassigned HDFS-16127: --------------------------------- Assignee: Kihwal Lee > Improper pipeline close recovery causes a permanent write failure or data > loss. > ------------------------------------------------------------------------------- > > Key: HDFS-16127 > URL: https://issues.apache.org/jira/browse/HDFS-16127 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Kihwal Lee > Assignee: Kihwal Lee > Priority: Major > > When a block is being closed, the data streamer in the client waits for the > final ACK to be delivered. If an exception is received during this wait, the > close is retried. This assumption has become invalid by HDFS-15813, resulting > in permanent write failures in some close error cases involving slow nodes. > There are also less frequent cases of data loss. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
