Minho Kim updated HAMA-848:
---------------------------
Attachment: HAMA_YARN06.patch
Hi,
I have some questions.
I don't know why configuration xml file is changed after call
reWriteSubmiConfigurations() in BSPApplicationMaster.java.
{code}
private static void rewriteSubmitConfiguration(String path, Configuration conf)
throws IOException {
Path jobSubmitPath = new Path(path);
FileSystem fs = FileSystem.get(conf);
FSDataOutputStream out = fs.create(jobSubmitPath);
conf.writeXml(out);
out.close();
fs.copyToLocalFile(false, jobSubmitPath, new Path("/root/job1.xml"));
LOG.info("Written new configuration back to " + path);
}
{code}
Another question is that BSPJob.writeXML() is supposed to save job
configuration such as user-defined value, user-modified value, but it was not
saved.
{code}
// In BSPJobClient.java
// Write job file to BSPMaster's fs
FSDataOutputStream out = FileSystem.create(fs, submitJobFile,
new FsPermission(JOB_FILE_PERMISSION));
try {
job.writeXml(out);
} finally {
out.close();
}
{code}
