Chackaravarthy resolved HDFS-10365. ----------------------------------- Resolution: Not A Bug Closing this jira as the issue was resolved after increasing {{dfs.blockreport.initialDelay}} value. Thanks for all the inputs. > FullBlockReports retransmission delays NN startup time in large cluster. > ------------------------------------------------------------------------ > > Key: HDFS-10365 > URL: https://issues.apache.org/jira/browse/HDFS-10365 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs > Affects Versions: 2.6.0 > Environment: version - hadoop-2.6.0 (hdp-2.2) > DN - 1200 nodes > Reporter: Chackaravarthy > Priority: Critical > > Whenever NN is restarted, it takes huge time for NN to come back to stable > state. i.e. Last contact time remains more than 1 or 2 mins continuously for > around 3 to 4 hours. This is mainly because most of the DN's getting timeout > (60s) in blockReport (FBR) rpc call and then it keep sending FBR again. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
