----------------------------------
Summary: Add support for yarn logs -logFile to retain backward
compatibility
Key: YARN-10312
URL: https://issues.apache.org/jira/browse/YARN-10312
Project: Hadoop YARN
Issue Type: Bug
Components: client
Affects Versions: 2.10.0, 3.4.1
Reporter: Jim Brennan
The YARN CLI logs command line option {{-logFiles}} was changed to
{{-log_files}} in 2.9 and later releases. This change was made as part of
YARN-5363.
Verizon Media is in the process of moving from Hadoop-2.8 to Hadoop-2.10, and
while testing integration with Spark, we ran into this issue. We are
concerned that we will run into more cases of this as we roll out to
production, and rather than break user scripts, we'd prefer to add
{{-logFiles}} as an alias of {{-log_files}}. If both are provided,
{{-logFiles}} will be ignored.
