apache pig - Perform arithmetic operation Pig -

-

i want make query hbase pig. rowkeys stored using reverse timestamp (long.max_value - timestamp). pig script, want store in variable current date in format (long.max_value - currenttime) query.

load 'mydata' using org.apache.pig.backend.hadoop.hbase.hbasestorage('d:column', '-caster=hbasebinaryconverter -gte $minrowkey* -lte $maxrowkey -loadkey true' ) (rowkey:chararray,json:chararray);

so this:

%default maxrowkey "date +%s"

and perform subtraction long.max_value - maxrowkey query. possible ?

thanks

i did not know of existence of hbasestorage options:

-mintimestamp= scan's timestamp min timerange

-maxtimestamp= scan's timestamp max timerange

that did trick me.
