liyunzhang_intel updated PIG-4920:
----------------------------------
Description:
udf.pig
{code}
register '/home/zly/prj/oss/merge.pig/pig/bin/udf.js' using javascript as
myfuncs;
A = load './passwd' as (a0:chararray, a1:chararray);
B = foreach A generate myfuncs.helloworld();
store B into './udf.out';
{code}
udf.js
{code}
helloworld.outputSchema = "word:chararray";
function helloworld() {
return 'Hello, World';
}
complex.outputSchema = "word:chararray";
function complex(word){
return {word:word};
}
{code}
run udf.pig in spark local mode(export SPARK_MASTER="local"), it successfully.
run udf.pig in spark yarn client mode(export SPARK_MASTER="yarn-client"), it
fails and error message like following:
