Inigo Goiri created HADOOP-12173:
------------------------------------
Summary: NetworkTopology#add calls NetworkTopology#toString always
Key: HADOOP-12173
URL: https://issues.apache.org/jira/browse/HADOOP-12173
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.7.0
Reporter: Inigo Goiri
Fix For: 2.7.1
It always does a toString of the whole topology but this is not required when
there are no errors. This is adding a very big overhead to large clusters as
it's walking the whole tree every time we add a node to the cluster.
HADOOP-10953 did some fix in that area but the errors is still there.
