             Summary: libhdfs client error message for "file not found" includes lengthy, unneeded stack trace
                 Key: HDFS-17791
                 URL: https://issues.apache.org/jira/browse/HDFS-17791
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: libhdfs
    Affects Versions: 3.3.6
            Reporter: Carl Vuosalo


The {{libhdfs}} client outputs a full Java stack trace in its error message for a "file not found" error. 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],
