Kousuke Saruta created HADOOP-10118:
---------------------------------------
Summary: CommandFormat never parse "--"
Key: HADOOP-10118
URL: https://issues.apache.org/jira/browse/HADOOP-10118
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 3.0.0
Reporter: Kousuke Saruta
We cannot use "--" option to skip args following that.
CommandFormat#parse is implemented as follows.
{code}
public void parse(List<String> args) {
...
} else if (arg.equals("--")) { // force end of option processing
args.remove(pos);
break;
}
...
{code}
But, FsShell is called through ToolRunner and ToolRunner use
GenericOptionParser. GenericOptionParser use GnuParser, which discard "--" when
parsing args.
