dark_num created HDFS-15552: ------------------------------- Summary: Let DeadNode Detector also work for EC cases Key: HDFS-15552 URL: https://issues.apache.org/jira/browse/HDFS-15552 Project: Hadoop HDFS Issue Type: Sub-task Components: dfsclient, ec Affects Versions: 3.3.0 Reporter: dark_num Fix For: 3.4.0
Currently, the EC stream (`DFSStripedInputStream`) is not handled properly while exception occurs. For example, while reading EC-blocks, if the client timed out when connecting to the DataNode, it will throws `SocketTimeoutException` , then add current DN to localDeadNode. However, the local dead nodes will not be removed until the stream is closed, which will cause *missing block IOException* to be thrown in the use scenario of Hbase. So we need to use detector to deal with dead nodes under EC to avoid reading failures. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
