Vinod Kumar Vavilapalli updated HADOOP-12125: --------------------------------------------- Target Version/s: 2.7.4 (was: 2.7.3) 2.7.3 is under release process, changing target-version to 2.7.4. > Retrying UnknownHostException on a proxy does not actually retry hostname > resolution > ------------------------------------------------------------------------------------ > > Key: HADOOP-12125 > URL: https://issues.apache.org/jira/browse/HADOOP-12125 > Project: Hadoop Common > Issue Type: Bug > Components: ipc > Reporter: Jason Lowe > Assignee: Rushabh S Shah > > When RetryInvocationHandler attempts to retry an UnknownHostException the > hostname fails to be resolved again. The InetSocketAddress in the > ConnectionId has cached the fact that the hostname is unresolvable, and when > the proxy tries to setup a new Connection object with that ConnectionId it > checks if the (cached) resolution result is unresolved and immediately throws. > The end result is we sleep and retry for no benefit. The hostname resolution > is never attempted again. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
