Daryn Sharp created HDFS-7005: --------------------------------- Summary: DFS input streams do not timeout Key: HDFS-7005 URL: https://issues.apache.org/jira/browse/HDFS-7005 Project: Hadoop HDFS Issue Type: Bug Components: hdfs-client Affects Versions: 2.5.0, 3.0.0 Reporter: Daryn Sharp Assignee: Daryn Sharp Priority: Critical
Input streams lost their timeout. The problem appears to be {{DFSClient#newConnectedPeer}} does not set the read timeout. During a temporary network interruption the server will close the socket, unbeknownst to the client host, which blocks on a read forever. The results are dire. Services such as the RM, JHS, NMs, oozie servers, etc all need to be restarted to recover - unless you want to wait many hours for the tcp stack keepalive to detect the broken socket. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
