Streaming's TextOutputReader.getLastOutput throws NPE if it has never read any
output
-------------------------------------------------------------------------------------
Key: MAPREDUCE-1621
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1621
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: contrib/streaming
Affects Versions: 0.20.2, 0.21.0, 0.22.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
If TextOutputReader.readKeyValue() has never successfully read a line, then its
bytes member will be left null. Thus when logging a task failure,
PipeMapRed.getContext() can trigger an NPE when it calls
outReader_.getLastOutput().
