Yongjun Zhang created HDFS-9474:
-----------------------------------
Summary: TestPipelinesFailover would fail if ifconfig is not
available
Key: HDFS-9474
URL: https://issues.apache.org/jira/browse/HDFS-9474
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Yongjun Zhang
HDFS-6693 introduced some debug message to debug why when TestPipelinesFailover
fails.
HDFS-9438 restricted the debug message to Linux/Mac/Solaris. However, the test
would fail when printing debug message if "ifconfig" command is not available
in certain environment.
This is not quite right. The test should not fail due to the debug message
printing. We should catch any exception thrown from the code that prints debug
message, and issue a warning message.
Suggest to make this change.
