Review Comment:
Why not unwrap RTE with both `MetaException` as well as
`InvalidOperationException` and translate to
`org.apache.hadoop.hive.metastore.api.AlreadyExistsException` . Since all the
callers of `alterTable` is already handling
`org.apache.hadoop.hive.metastore.api.AlreadyExistsException`.
I am thinking something like this:
```
catch (RuntimeException e) {
// MetaException would be wrapped into RuntimeException during
reflection
if (e.getCause() instanceof MetaException) {
throw (MetaException) e.getCause();
}
// InvalidOperationException would be wrapped into RuntimeException
during reflection, as
// java.lang.RuntimeException:InvalidOperationException(message:new
table <> already exists)
if (e.getCause() instanceof InvalidOperationException
&& e.getCause().getMessage() != null
&& e.getCause()
.getMessage()
.contains(
String.format(
"new table %s.%s already exists",
table.getDbName(), table.getTableName()))) {
throw new AlreadyExistsException(
String.format("Table already exists: %s.%s",
table.getDbName(), table.getTableName()));
}
throw e;
}
```
