Steve Loughran created HADOOP-8629:
--------------------------------------
Summary: Add option for TableMapping to reload mapping file on
match failure
Key: HADOOP-8629
URL: https://issues.apache.org/jira/browse/HADOOP-8629
Project: Hadoop Common
Issue Type: Improvement
Components: util
Reporter: Steve Loughran
Priority: Minor
As commented in HADOOP-7030, the table mapping topology mapper handles new node
addition worse than the script mapping, because the table mapping is frozen for
the life of the service.
I propose adding an option (true by default?) for the class to look at the
timestamp of the mapping file, and reload it on a change -if a hostname lookup
failed.
