Lantao Jin resolved HDFS-11360. ------------------------------- Resolution: Duplicate Assignee: Lantao Jin > HDFS balancer need a config to appoint to a decided nameservice > --------------------------------------------------------------- > > Key: HDFS-11360 > URL: https://issues.apache.org/jira/browse/HDFS-11360 > Project: Hadoop HDFS > Issue Type: Bug > Components: balancer & mover > Affects Versions: 2.7.1 > Reporter: Lantao Jin > Assignee: Lantao Jin > Priority: Minor > > With distcp configuration, there are two or more "nameservices" setting in > hdfs-site.xml, for example: > {code} > <property> > <name>dfs.nameservices</name> > <value>one-nn-ha,two-nn-ha</value> > </property> > {code} > If the HDFS Balancer also launches in that node, it will create two IPC > threads to connect both of NNs. And block removing both happens in this > Balancer. Although I didn't find any block removing between different > clusters, the behavior still became weird and unexpected. > So the best way is adding a configuration that appoint to a decided > nameservice to launch. I can offer a patch. Any better ideal? -- 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
