hbase/spark版本的这种组合似乎是相当有害的。我花了几个小时试图找到各种合并策略的工作，但没有结果。
以下是当前build.sbt的核心：

val sparkVersion = "1.0.0"
// val sparkVersion = "1.1.0-SNAPSHOT"

val hbaseVersion = "0.96.1.1-cdh5.0.2"

libraryDependencies ++= Seq(
    "org.apache.hbase" % "hbase-client" % hbaseVersion,
    "org.apache.hbase" % "hbase-common" % hbaseVersion,
    "org.apache.hbase" % "hbase-server" % hbaseVersion,
    "org.apache.hbase" % "hbase-protocol" % hbaseVersion,
    "org.apache.hbase" % "hbase-examples" % hbaseVersion,
  ("org.apache.spark" % "spark-core_2.10" % sparkVersion  withSources()).excludeAll(ExclusionRule("org.mortbay.jetty")),
  "org.apache.spark" % "spark-sql_2.10" % sparkVersion  withSources()
)

以下是不可避免地出现的错误消息：
