 Once we start allowing joins and subqueries, we have a whole bunch of table aliases and relationships to deal with. We have to contend with name clashes, self-joins, as well as scoping rules. In a way, the vschema has acted as a static symbol table so far. But that’s not going to be enough any more.
 
-The core of the symbol table will contain a map whose key will be a table alias, and the elements will be [similar to the table in vschema](https://github.com/vitessio/vitess/blob/master/go/vt/vtgate/planbuilder/schema.go#L22). However, it will also contain a column list that will be built as the query is parsed.

 Let's say we want to write a MapReduce job that imports this table from Vitess to HDFS where each row is turned into a CSV record in HDFS. 
 
-We can use [VitessInputFormat](https://github.com/vitessio/vitess/blob/master/java/hadoop/src/main/java/io/vitess/hadoop/VitessInputFormat.java), an implementation of Hadoop's [InputFormat](https://hadoop.apache.org/docs/stable/api/org/apache/hadoop/mapred/InputFormat.html), for that. With VitessInputFormat, rows from the source table are streamed to the mapper task. Each input record has a [NullWritable](https://hadoop.apache.org/docs/r2.2.0/api/org/apache/hadoop/io/NullWritable.html) key (no key, really), and [RowWritable](https://github.com/vitessio/vitess/blob/master/java/hadoop/src/main/java/io/vitess/hadoop/RowWritable.java) as value, which is a writable implementation for the entire row's contents.
