> Reporter: Carl Vuosalo
> Priority: Minor
> Labels: pull-request-available
>
> 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],
