Subject [jira] [Commented] (HDFS-3390) DFSAdmin should print full stack traces of errors when DEBUG logging is enabled
Date Tue, 08 May 2012 23:29:49 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13270924#comment-13270924
] 

Tsz Wo (Nicholas), SZE commented on HDFS-3390:
----------------------------------------------

The double try-catch makes the code hard to read.  How about either 
- print the debug message in individual catch block, or
- set assign the exception to a local variable and the print the debug message outside before
the return?

> If an error is encountered when running an `hdfs dfsadmin ...' command, only the exception's
message is output. It would be handy for debugging if the full stack trace of the exception
were output when DEBUG logging is enabled.
