Summary: Initial implementation of TezCompiler
Key: PIG-3500
URL: https://issues.apache.org/jira/browse/PIG-3500
Project: Pig
Issue Type: Sub-task
Components: tez
Affects Versions: tez-branch
Reporter: Cheolsoo Park
Assignee: Cheolsoo Park
Fix For: tez-branch
Implement TezCompiler that compiles physical plan into tez plan. To begin with,
we can implement the initial version that works for basic queries as follows:
# Load-Filter-Store
{code}
a = load 'file:///tmp/input' as (x:int, y:int);
b = filter a by x > 0;
c = foreach b generate y;
store c into 'file:///tmp/output';
{code}
# Load-Filter-GroupBy-Store
{code}
a = load 'file:///tmp/input' as (x:int, y:int);
b = group a by x;
c = foreach b generate group, a;
store c into 'file:///tmp/output';
{code}
# Load1-Load2-Join-Store
{code}
a = load 'file:///tmp/input1' as (x:int, y:int);
b = load 'file:///tmp/input2' as (x:int, z:int);
c = join a by x, b by x;
d = foreach c generate a::x as x, y, z;
store d into 'file:///tmp/output';
{code}
