回复: How did the RDD.union work

2014-11-11 Thread qiaou
ok here is the code

def hbaseQuery:(String)=RDD[Result] = {
  val generateRdd = (area:String)={
val startRowKey = s$area${RowKeyUtils.convertToHex(startId, 
10)}
val stopRowKey = s$area${RowKeyUtils.convertToHex(endId, 
10)}
println(sstartRowKey:${startRowKey})
println(sstopRowKey :${stopRowKey})

val scan = new Scan()
scan.setStartRow(Bytes.toBytes(startRowKey))
scan.setStopRow(Bytes.toBytes(stopRowKey))
val filterList: FilterList = new FilterList()
if (appKey != null  !appKey.equals(_)) {
  val appKeyFilter: SingleColumnValueFilter =
new SingleColumnValueFilter(Bytes.toBytes(clientInfo), 
Bytes.toBytes(optKey), CompareOp.EQUAL, Bytes.toBytes(appKey))
  filterList.addFilter(appKeyFilter)
}
if (imei != null  !imei.equals(_)) {
  val imeiFilter: SingleColumnValueFilter =
new SingleColumnValueFilter(Bytes.toBytes(clientInfo), 
Bytes.toBytes(optImei), CompareOp.EQUAL, Bytes.toBytes(imei))
  filterList.addFilter(imeiFilter)
}
if (filterList.getFilters != null  filterList.getFilters.size()  0) {
  scan.setFilter(filterList)
}
scan.setCaching(1)

val hbaseConf = HBaseConfigUtil.getHBaseConfiguration
hbaseConf.set(TableInputFormat.INPUT_TABLE, asrLogFeedBack)
hbaseConf.set(TableInputFormat.SCAN, 
Base64.encodeBytes(ProtobufUtil.toScan(scan).toByteArray))

SparkUtil.getSingleSparkContext()
  .newAPIHadoopRDD(hbaseConf, classOf[TableInputFormat],
classOf[ImmutableBytesWritable], classOf[Result]).map {
  case (_: ImmutableBytesWritable, result: Result) = {
result
  }
}
  }
  return generateRdd
}

 Could you provide the code of hbaseQuery? It maybe doesn't support to execute 
 in parallel.

  Hi:  
  I got a problem with using the union method of RDD
  things like this
  I get a function like
  def hbaseQuery(area:string):RDD[Result]= ???
  when i use hbaseQuery('aa').union(hbaseQuery(‘bb’)).count() it 
  returns 0
  however when use like this  sc.parallize(hbaseQuery('aa’).collect.toList 
  ::: hbaseQuery(’bb’).collect.toList).count() it return the right value  
  obviously i have got an action after my transformation action ,but why it 
  did not work
  fyi

 You need to create a new configuration for each RDD. Therefore, val 
 hbaseConf = HBaseConfigUtil.getHBaseConfiguration should be changed to val 
 hbaseConf = new Configuration(HBaseConfigUtil.getHBaseConfiguration)
