Hello,
I am facing Spark serialization issue in Spark (1.4.1 - Java Client) with
Spring Framework. It is known that Spark needs serialization and it requires
every class need to be implemented with java.io.Serializable. But, in the
documentation link:
springBootVersion = '1.2.8.RELEASE'
springDIVersion = '0.5.4.RELEASE'
thriftGradleVersion = '0.3.1'
Other Gradle configs:
compile "org.apache.thrift:libthrift:0.9.3"
compile 'org.slf4j:slf4j-api:1.7.14'
compile 'org.apache.kafka:kafka_2.11:0.9.0.0'
compile
Even If I m using this query then also give NullPointerException:
"SELECT clientId FROM activePush"

Your question is very interesting. What I suggest is, that copy your output
in some text file. Read text file in your code and apply RDD. Just consider
wordcount example by Spark. I love this example with Java client. Well,
Spark is an analytical engine and it has a slogan to analyze big big data
I have almost the same case. I will tell you what I am actually doing, if it
is according to your requirement, then I will love to help you.

Rusty,
I am very thankful for your help. Actually, I am facing difficulty in
objects. My plan is that, I have an object list containing list of User
objects. After parallelizing it through spark context, I apply comparator
on user.getUserName(). As usernames are sorted, their related user object
