Keith Dsouza updated PIG-3477:
------------------------------
Description:
Pig does not evaluate statements in sequence and evaluates the *nix statement
(RMF, MV) encountered first and then processes the rest of the PIG statements
which makes it impossible to sequentially use both PIG statements as well as
Unix statements in a job.
For example:
I want to read data from A and A_new_data and store it in A, I use this
LOAD A
-- Read and merge A and A.new and create A_new_data
RMF A
STORE A_new_data into A
was:
Pig does not evaluate statements in sequence and evaluates the first *nix
statement encountered first and then processes the rest of the PIG statements
till it encounters another PIG statement which makes it hard to sequentially
use both PIG statements as well as Unix statements useless in a sequence.
For example:
I want to read data from A and A_new_data and store it in A, I use this
LOAD A
-- Read and merge A and A.new and create A_new_data
RMF A
STORE A_new_data into A
> *Nix commands do not execute sequentially
