liyunzhang_intel updated PIG-5246:
----------------------------------
Attachment: PIG-5246.patch
[~nkollar], [~szita]: help review
in spark2, spark-assembly*.jar does not exist, so we need append all jars under
$SPARK_HOME/jars/ to the pig classpath.
{code}
+ if [ "$sparkversion" == "21" ]; then
+ if [ -n "$SPARK_HOME" ]; then
+ echo "Using Spark Home: " ${SPARK_HOME}
+ for f in $SPARK_HOME/jars/*.jar; do
+ CLASSPATH=${CLASSPATH}:$f
+ done
+ fi
+ fi
{code}
the way to use
1. build pig with spark21
{noformat}
ant clean -v -Dsparkversion=21 -Dhadoopversion=2 jar
{noformat}
2. run pig with spark21
{noformat}
/pig -x $mode -sparkversion 21 -log4jconf $PIG_HOME/conf/log4j.properties
-logfile $PIG_HOME/logs/pig.log $PIG_HOME/bin/testJoin.pig
{noformat}
> Modify bin/pig about SPARK_HOME, SPARK_ASSEMBLY_JAR after upgrading spark to 2
