HBase Spark Streaming giving error after restore
Hi All,
I am using below code to stream data from kafka to hbase ,everything works
fine until i restart the job so that it can restore the state from
checkpoint directory ,but while trying to restore the state it give me below

}
)
put
}

Re: HBase Spark Streaming giving error after restore
Can you show the complete stack trace ?
Subclass of Mutation is expected. Put is a subclass.
Have you tried replacing BoxedUnit with Put in your code ?
Cheers
