Review Comment:
`HiveMetaTool.main` is called from several test example:
https://github.com/apache/hive/blob/36ce858163a19e29eafe4a8d3307191bc28fc175/itests/hive-unit/src/test/java/org/apache/hadoop/hive/metastore/tools/metatool/TestHiveMetaTool.java#L185-L187
and adding `System.exit` call causes

```
How about refactor the main by extracting the try block to a method and this
new method would be called from tests:
```
static void createAndExecuteTask(HiveMetaToolCommandLine cl) {
if (cl.isListFSRoot()) {
task = new MetaToolTaskListFSRoot();
...
task.execute();
}
main(String[] args) {
HiveMetaToolCommandLine cl = HiveMetaToolCommandLine.parseArguments(args);
...
try {
createAndexecuteTask(cl);
}
catch (Exception ex) {
System.exit(-1);
}
finally {
...
}
System.exit(-1);
}
@Test
public void testListFSRoot() throws Exception {
HiveMetaToolCommandLine cl = HiveMetaToolCommandLine.parseArguments(new
String[] {"-listFSRoot"});
HiveMetaTool.createAndExecuteTask(cl);
...
}
```
