----------------------------------
Summary: a minor concurrent bug inside NetworkTopology
Key: HADOOP-10953
URL: https://issues.apache.org/jira/browse/HADOOP-10953
Project: Hadoop Common
Issue Type: Bug
Components: net
Affects Versions: 3.0.0
Reporter: Liang Xie
Assignee: Liang Xie
Priority: Minor
Found this issue while reading the related code. In NetworkTopology.toString()
method, there is no thread safety guarantee directly, it's called by
add/remove, and inside add/remove, most of this.toString() calls are protected
by rwlock, except a couple of error handling codes, one possible fix is that
moving them into lock as well, due to not heavy operations, so no obvious
downgration should be observed per my current knowledge.
