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

dfs.namenode.replication.work.multiplier.per.iteration -- 20

 

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