--------------------------------
Summary: avoid printing stack information for SafeModeException
Key: HDFS-3817
URL: https://issues.apache.org/jira/browse/HDFS-3817
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Brandon Li
Assignee: Brandon Li
When NN is in safemode, any namespace change request could cause a
SafeModeException to be thrown and logged in the server log, which can make the
server side log grow very quickly.
The server side log can be more concise if only print the exception and error
message will be printed but not the stack track.
