hbase Read issue - Json Mapping error

[sraghav]

We are reading from a secured hbase cluster, and facing the following issue -

Exception in thread "main" com.fasterxml.jackson.databind.JsonMappingException: No suitable constructor found for type [simple type, class org.apache.spark.rdd.RDDOperationScope]: can not instantiate from JSON object (need to add/enable type information?)

the actual content form the table is plain String. The source code for the same is fairly straightforward -

val hBaseRDD = sparkContext.hbaseTable[(String)]("myDB:test").select("123456789").inColumnFamily("m")
hBaseRDD.take(10)

We have provided the hbase quorum information through hbase-site.xml in the packaged jar file.
