本文介绍了一个在使用Spark Scala代码读取HBase表时遇到的非序列化异常问题，并给出了通过配置Kryo序列化器来解决此问题的方法。
During reading htable via spark scala code, the following error happened:

15/10/28 16:39:00 WARN scheduler.TaskSetManager: Lost task 0.0 in stage 10.0 (TID 2536, slave14.dc.tj): java.lang.RuntimeException: java.io.NotSerializableException: org.apache.hadoop.hbase.io.ImmutableBytesWritable
Serialization stack:
        - object not serializable (class: org.apache.hadoop.hbase.io.ImmutableBytesWritable, value: 30 30 5f 39 39 39 38 38 33)
        - field (class: scala.Tuple2, name: _1, type: class java.lang.Object)

        at org.apache.spark.serializer.JavaSerializationStream.writeObject(JavaSerializer.scala:47)

        ......

The solution is turn spark to use KryoSerializer:
sparkconf.set("spark.serializer", "org.apache.spark.serializer.KryoSerializer")

已经extends Serializable 但是因为类里有个对象没有extends Serializable 所以报这个错 把这个对象放到一个比如init()方法里 以及其他地方修改下 即可
