Suggest to allow PigServer can register pig script from InputStream
-------------------------------------------------------------------
Key: PIG-1675
URL: https://issues.apache.org/jira/browse/PIG-1675
Project: Pig
Issue Type: Improvement
Affects Versions: 0.8.0
Reporter: Jeff Zhang
Assignee: Jeff Zhang
Fix For: 0.8.0
Currently, Pig only allow users to register script from file. Although it
satisfy most people's requirements, sometimes people hope to build pig script
dynamically using code, then they need to create temp file for the script they
build. So here I suggest to allow PigServer be able to register pig script from
InputStream.
InputStream is a more general type than File, pig script can been from file
(FileInputStream)
or from in-memory (ByteArrayInputStream) even it can been from remote machines
(SocketInputStream)
Here's a blog which explains why using InputStream is better than using File in
interface http://java.dzone.com/articles/using-files-your-interfaces-0
So I suggest to add the following 4 methods in PigServer:
{code}
public void registerScript(InputStream in) throws IOException
public void registerScript(InputStream in, Map<String,String> params) throws
IOException
public void registerScript(InputStream in, List<String> paramsFiles) throws
IOException
public void registerScript(InputStream in, Map<String,String>
params,List<String> paramsFiles) throws IOException
{code}
