Accessing stderr with Hadoop Streaming
Is there a way to access stderr when using Hadoop Streaming? I see how stdout is written to the log files but I'm more concerned about what happens when errors occur. Access to stderr would help debug when a run doesn't complete successfully but I haven't been able to figure out how to retrieve what's written to stderr. Presumably another approach would be to redirect stderr to stdout but I wanted to exhaust other approaches before trying that. Thanks, SD

Thanks, SD I normally see whats been written to stderr through the web interface. They're in the 'userlogs' directory in /opt/hadoop/logs. M
