After PIG-3359, the way we cache parameter substitution results changed a bit. {code:title=test.pig} A = load 'input.txt' ; %declare output '/tmp/abc'; %declare actualoutput '$output.out'; store A into '$actualoutput'; %declare output '/tmp/def'; %declare actualoutput '$output.out'; store A into '$actualoutput'; %declare number '1d'; %declare shellout `bash -c "date -v-$number +'%Y%m%d_%H:%S_%s'; sleep 1" ` store A into '$shellout'; %declare shellout `bash -c "date -v-$number +'%Y%m%d_%H:%S_%s'; sleep 1" ` store A into '$shellout'; %declare number '2d'; %declare shellout `bash -c "date -v-$number +'%Y%m%d_%H:%S_%s'; sleep 1" ` store A into '$shellout'; {code} Result from pig 0.11 (almost correct) {panel} A = load 'input.txt' ; store A into '/tmp/abc.out'; store A into '/tmp/def.out'; store A into '20160515_17:32_1463346752'; store A into '20160515_17:33_1463346753'; {color:red}NO{color} store A into '20160514_17:34_1463260354'; {panel} Result from trunk {panel} A = load 'input.txt' ; store A into '/tmp/abc.out'; store A into '/tmp/abc.out'; {color:red} NO{color} store A into '20160515_15:10_1463338810'; store A into '20160515_15:10_1463338810'; store A into '20160515_15:10_1463338810'; {color:red}NO{color} {panel} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
