Carl Vuosalo updated HDFS-17791:
--------------------------------
Description:
The {{libhdfs}} client outputs a full Java stack trace in its error message for
a "file not found" error when trying to open a non-existent file. Our HDFS
application processes numerous queries checking for the presence of files, so
"file not found" errors are frequent. Each such error generates a very lengthy
and useless Java stack trace. These traces have no diagnostic value, since the
cause of the error is that the file doesn't exist.
A fix for this problem is proposed by pull request
[#7696|https://github.com/apache/hadoop/pull/7696],
