How physical translator works at the time of compilation of pig query
After the logical plan is generated,script executation moves to the physical plan, Apache script will use to execute the pig script. During the creation of physical plan, co-group logical operator is converted into three physical operators namely : Local Rearrange, Global Rearrange and Package.
