Yuexin Zhang created HBASE-18570:

             Summary: use hbase-spark without HBaseContext runs into NPE
                 Key: HBASE-18570
                 URL: https://issues.apache.org/jira/browse/HBASE-18570
             Project: HBase
          Issue Type: Improvement
          Components: hbase
    Affects Versions: 1.2.0
            Reporter: Yuexin Zhang
            Priority: Minor

I recently run into the same issue as described in stackoverflow :


If we don't explicitly initialize a HBaseContext and don't set 
hbase.use.hbase.context option to false, it will run into NPE at:
    val wrappedConf = new SerializableConfiguration(hbaseContext.config)


Should we safe guard with a NULL validation  on hbaseContext?

Something like: 
    //create or get latest HBaseContext
  val hbaseContext:HBaseContext = if (useHBaseContext && null != 
LatestHBaseContextCache.latest) {
  } else {
    val config = HBaseConfiguration.create()
    configResources.split(",").foreach( r => config.addResource(r))
    new HBaseContext(sqlContext.sparkContext, config)
