Karthik Kambatla updated HDFS-6221: ----------------------------------- Target Version/s: 2.6.0 (was: 3.0.0, 2.5.0) > Webhdfs should recover from dead DNs > ------------------------------------ > > Key: HDFS-6221 > URL: https://issues.apache.org/jira/browse/HDFS-6221 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode, webhdfs > Affects Versions: 2.0.0-alpha, 3.0.0 > Reporter: Daryn Sharp > Assignee: Daryn Sharp > > We've repeatedly observed the jetty acceptor thread silently dying in the > DNs. The webhdfs servlet may also "disappear" and jetty returns non-json > 404s. > One approach to make webhdfs more resilient to bad DNs is dfsclient-like > fetching of block locations to directly access the DNs instead of relying on > a NN redirect that may repeatedly send the client to the same faulty DN(s). -- This message was sent by Atlassian JIRA (v6.2#6252)
