Hello,
I'm using HBaseStorage and I want to change the layout of the schema
before storage. Specifically I want to group some values into a tuple
(thus reducing the number of repetitions of the row and column keys).
Even though the JavaDoc gives an example that uses AS schema Grunt
complains that it is not parsable. Here's what I am trying:
STORE dataToStore INTO 'hbase://tableName' USING
HBaseStorage('cf:tuple, cf:date') AS TOTUPLE(val1, val2, val3), date;
Is this possible? Or do I have to do the transformation in a separate step:
dataTransformed = FOREACH dataToStore GENERATE TOTUPLE(val1, val2,
val3), date;
In case of the latter, can Pig be told to merge this step with the
next one? I tried a nested FOREACH where I can have an assignment
operation, but I quickly found out that STORE is not supported within
the FOREACH.. what was I thinking :).
Thanks!
