解决:
库冲突,删除javax.servlet开头的库

See my answer to a similar question here. The class conflict comes about because HBase depends on org.mortbay.jetty, and Spark depends on org.eclipse.jetty. I was able to resolve the issue by excluding org.mortbay.jetty dependencies from HBase.
If you're pulling in hadoop-common, then you may also need to exclude javax.servlet from hadoop-common. I have a working HBase/Spark setup with my sbt dependencies set up as follows:
val hadoopCommon = "org.apache.hadoop" % "hadoop-common" % hadoopVersion % "provided" excludeAll ExclusionRule(organization = "javax.servlet")
val hbaseCommon = "org.apache.hbase" % "hbase-common" % hbaseVersion % "provided"
val hbaseClient = "org.apache.hbase" % "hbase-client" % hbaseVersion % "provided"
val hbaseProtocol = "org.apache.hbase" % "hbase-protocol" % hbaseVersion % "provided"
val hbaseHadoop2Compat = "org.apache.hbase" % "hbase-hadoop2-compat" % hbaseVersion % "provided"
val hbaseServer = "org.apache.hbase" % "hbase-server" % hbaseVersion % "provided" excludeAll ExclusionRule(organization = "org.mortbay.jetty")
val sparkCore = "org.apache.spark" %% "spark-core" % sparkVersion % "provided"
val sparkStreaming = "org.apache.spark" %% "spark-streaming" % sparkVersion % "provided"
val sparkStreamingKafka = "org.apache.spark" %% "spark-streaming-kafka" % sparkVersion exclude("org.apache.spark", "spark-streaming_2.10")
