I have two strings that I want to concatenate. The first one holds a number and
coming from this set of commands:
library = LOAD 'discovery_library' USING
org.apache.pig.backend.hadoop.hbase.HBaseStorage('A:TISSUE' ,'-loadKey true')
as (id:int, name:chararray);
grpd = group library all;
data = foreach grpd generate MAX(library.id) as id;
The second one is a root path.
root_path = '/user/zahra/Sequence/data/';
I want to concatenate these two and create new path. For example if data=268, I
would like to have : '/user/zhaji/Sequence/data/268'
When I used CONCAT(root_path, data), I got this error:
ERROR 1000: Error during parsing. Lexical error at line 15, column 14.
Encountered: "/" (47), after : "\""
Which is pointing to path assignment to roo_path variable!
Thanks for any help.
