MapReduceLauncher squashes unchecked exceptions
-----------------------------------------------
Key: PIG-2648
URL: https://issues.apache.org/jira/browse/PIG-2648
Project: Pig
Issue Type: Bug
Components: impl
Reporter: Alex Levenson
in:
org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher.JobControlThreadExceptionHandler
{code}
jobControlExceptionStackTrace = getStackStraceStr(throwable);
try {
jobControlException = getExceptionFromString(jobControlExceptionStackTrace);
} catch (Exception e) {
String errMsg = "Could not resolve error that occured when launching map
reduce job: "
+ jobControlExceptionStackTrace;
jobControlException = new RuntimeException(errMsg);
}
{code}
The catch clause does not chain the original exception, this made tracking
down: https://issues.apache.org/jira/browse/PIG-2645 a lot more difficult.
