Amar Kamat commented on HADOOP-2344: ------------------------------------ The way the Exception message is composed should be changed. Basically its composed of - Error stream output - Exit code error message So {code} exitCode = process.waitFor(); if (exitCode != 0) { if (errMsg.length() == 0) { errMsg.append("Command exit with status code " + exitCode); } throw new IOException(errMsg.toString()); } completed = true; {code} should be changed to {code} exitCode = process.waitFor(); if (exitCode != 0) { if (errMsg.length() == 0) { errMsg.insert(0,"Command exit with status code " + exitCode + ",\n"); } throw new IOException(errMsg.toString()); } completed = true; {code} > Free up the buffers (input and error) while executing a shell command before > waiting for it to finish. > ------------------------------------------------------------------------------------------------------ > > Key: HADOOP-2344 > URL: https://issues.apache.org/jira/browse/HADOOP-2344 > Project: Hadoop > Issue Type: Bug > Affects Versions: 0.16.0 > Reporter: Amar Kamat > Assignee: Amar Kamat > Fix For: 0.16.0 > > Attachments: HADOOP-2231.patch, HADOOP-2344.patch, HADOOP-2344.patch, > HADOOP-2344.patch, HADOOP-2344.patch, HADOOP-2344.patch, HADOOP-2344.patch > > > Process.waitFor() should be invoked after freeing up the input and error > stream.
