---------------------------
> Add aliases to ExecJobs and PhysicalOperators

> Key: PIG-1156
> URL: https://issues.apache.org/jira/browse/PIG-1156
> Project: Pig
> Issue Type: Improvement
> Reporter: Dmitriy V. Ryaboy
> Assignee: Dmitriy V. Ryaboy
> Fix For: 0.7.0
>
> Attachments: pig_batchAliases.patch
>
>
> Currently, the way to use muti-query from Java is as follows:
> 1. pigServer.setBatchOn();
> 2. register your queries with pigServer
> 3. List<ExecJob> jobs = pigServer.executeBatch();
> 4. for (ExecJob job : jobs) { Iterator<Tuple> results = job.getResults(); }
> This will cause all stores to get evaluated in a single batch. However, there
> is no way to identify which of the ExecJobs corresponds to which store. We
> should add aliases by which the stored relations are known to ExecJob in
> order to allow the user to identify what the jobs correspond do.
