Work on HDFS-15695 started by Ahmed Hussein. -------------------------------------------- > NN should not let the balancer run in safemode > ---------------------------------------------- > > Key: HDFS-15695 > URL: https://issues.apache.org/jira/browse/HDFS-15695 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Reporter: Ahmed Hussein > Assignee: Ahmed Hussein > Priority: Major > > [~daryn] reported that when the balancer moves a block, the target DN block > reports the new location and hints to invalidate the source DN. The NN will > not issue invalidations in safemode, so every moved block appears to be in > excess. The data structures bloat and greatly increase the chance of a full > GC. > The NN should refuse to provide block locations to the balancer while in > safemode. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
