Programs can return only an integer value to shell by calling
System.exit(10), default jvm return 0 on successfully exit. May be you can
write to stdout statement in main class(here LinkAnalytics,java) as last
statement to print out array entries or any other information and redirect
stdout to a file and read to buffer.
$hadoop jar
hbase-link-analytics-0.0.1-SNAPSHOT-jar-with-dependencies.jar
com.cloudsoftware.LinkAnalytics 101,102,103 20170101,20170103 > out.txt
2>&1 &
CONTENTS=$(cat out.txt)
