Pig TestGrunt.testShellCommand occasionally fails
-------------------------------------------------
Key: PIG-2499
URL: https://issues.apache.org/jira/browse/PIG-2499
Project: Pig
Issue Type: Bug
Components: build
Reporter: Tom White
The following code fails from time to time (with a NPE since
{{fileReader.readLine()}} returns null) :
{noformat}
strCmd = "sh bash -c 'touch TouchedFileInsideGrunt_61 | ls | grep
TouchedFileInsideGrunt_61 > fileContainingTouchedFileInsideGruntShell_71'";
cmd = new ByteArrayInputStream(strCmd.getBytes());
reader = new InputStreamReader(cmd);
grunt = new Grunt(new BufferedReader(reader), context);
grunt.exec();
fileReader = new BufferedReader(new
FileReader("fileContainingTouchedFileInsideGruntShell_71"));
assertTrue(fileReader.readLine().equals("TouchedFileInsideGrunt_61"));
{noformat}
