Under Replicated Blocks tuning

Under Replicated Blocks tuning

New Contributor

Hi Everyone,



First post on here:   We have a situation where we see under replicated blocks ~200K and are slowly getting replicated.   We wanted to see if there was a way to speed that process up.


Current settings:


dfs.namenode.replication.max-streams   -- 50

dfs.namenode.replication.max-streams-hard-limit -- 100 -- 20


Its a 4 datanode cluster that is sitting idle, network is about 15mb/seconds
