Zoran Dimitrijevic created HADOOP-13587:
-------------------------------------------
Summary: distcp.map.bandwidth.mb is overwritten even when
-bandwidth flag isn't set
Key: HADOOP-13587
URL: https://issues.apache.org/jira/browse/HADOOP-13587
Project: Hadoop Common
Issue Type: Bug
Components: tools/distcp
Affects Versions: 3.0.0-alpha1
Reporter: Zoran Dimitrijevic
Priority: Minor
distcp.map.bandwidth.mb exists in distcp-defaults.xml config file, but it is
not honored even when it is . Current code always overwrites it with either
default value (java const) or with -bandwidth command line option.
The expected behavior (at least how I would expect it) is to honor the value
set in distcp-defaults.xml unless user explicitly specify -bandwidth command
line flag. If there is no value set in .xml file or as a command line flag,
then the constant from java code should be used.
Additionally, I would expect that we also try to get values from
distcp-site.xml, similar to other hadoop systems.
