cnweike created HIVE-3259:
-----------------------------
Summary: public Table getTable(String dbName, String tableName)
throws MetaException Shoule log more detail content when exception happens
Key: HIVE-3259
URL: https://issues.apache.org/jira/browse/HIVE-3259
Project: Hive
Issue Type: Wish
Components: Metastore
Affects Versions: 0.8.0
Environment: CDH3u4 Hive 0.8
Reporter: cnweike
public Table get_table(final String dbname, final String name) throws
MetaException,
NoSuchObjectException {
Table t = null;
startTableFunction("get_table", dbname, name);
try {
t = executeWithRetry(new Command<Table>() {
@Override
Table run(RawStore ms) throws Exception {
Table t = ms.getTable(dbname, name);
if (t == null) {
throw new NoSuchObjectException(dbname + "." + name
+ " table not found");
}
return t;
}
});
} catch (NoSuchObjectException e) {
throw e;
} catch (MetaException e) {
throw e;
} catch (Exception e) {
assert(e instanceof RuntimeException);
throw (RuntimeException)e;
} finally {
endFunction("get_table");
}
return t;
}
when Table t = ms.getTable(dbname, name); returns null, it just throw a
exception, but why ? we cannot get any useful information from this exception
info, so I suggest log the exception information when ms.getTable(dbname, name)
really throw some exception.
