Lantao Jin created HDFS-11360: --------------------------------- Summary: HDFS balancer need 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 Reporter: 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 also happens in the this Balancer. Although I didn't find any block removing between different nodes, 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 (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
