I have found myself doing this manually in the best because of how long the NN can take to start up when it needs to process all of the edits. +1 from me. > keepResults option in NNThroughputBenchmark should call saveNamespace() > ----------------------------------------------------------------------- > > Key: HDFS-14502 > URL: https://issues.apache.org/jira/browse/HDFS-14502 > Project: Hadoop HDFS > Issue Type: Improvement > Affects Versions: 2.7.6 > Reporter: Konstantin Shvachko > Assignee: Konstantin Shvachko > Priority: Major > Attachments: HDFS-14502.001.patch > > > {{-keepResults}} option is usually used to make it possible to rerun > NNThroughputBenchmark with existing namespace state.

Otherwise NN startup takes a while since it needs to > digest large edits file starting from the empty image. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
