Keith Turner created ACCUMULO-826:
-------------------------------------
Summary: MapReduce over accumlo fails if process that started job
is killed
Key: ACCUMULO-826
URL: https://issues.apache.org/jira/browse/ACCUMULO-826
Project: Accumulo
Issue Type: Bug
Affects Versions: 1.4.0, 1.4.1
Reporter: Keith Turner
Priority: Critical
While testing the 1.4.2rc2 I started a continuous verify and killed the process
that started the job. Normally you would expect the job to keep running when
you do this. Howerver task started to fail. I was seeing errors like the
following.

I think this is caused by the following code in InputFormatBase
{code:java}
public static void setInputInfo(Configuration conf, String user, byte[]
passwd, String table, Authorizations auths) {
if (conf.getBoolean(INPUT_INFO_HAS_BEEN_SET, false))
throw new IllegalStateException("Input info can only be set once per
job");
conf.setBoolean(INPUT_INFO_HAS_BEEN_SET, true);
ArgumentChecker.notNull(user, passwd, table);
conf.set(USERNAME, user);
conf.set(TABLE_NAME, table);
if (auths != null && !auths.isEmpty())
conf.set(AUTHORIZATIONS, auths.serialize());
try {
FileSystem fs = FileSystem.get(conf);
Path file = new Path(fs.getWorkingDirectory(),
conf.get("mapred.job.name") + System.currentTimeMillis() + ".pw");
conf.set(PASSWORD_PATH, file.toString());
FSDataOutputStream fos = fs.create(file, false);
fs.setPermission(file, new FsPermission(FsAction.ALL, FsAction.NONE,
FsAction.NONE));
fs.deleteOnExit(file); // <--- NOT 100% sure, but I think this is the
culprit
{code}
