Sur une machine de signle j'ai installé hadoop-2.7.3, hbase-1.2.6 et étincelle 2.1.1. Avec une application étincelle j'essaye de lire des données de hbase mais j'obtiens toujours l'erreur d'expiration. Le code est en scala:Spark 2.1.1 - HBase 1.2.6 connexion délai d'attente zookeeper
object SparkHbaseTest {
def main(args: Array[String]) {
val sparkConf = new SparkConf().setAppName("Spark HBase Test")
val sc = new SparkContext(sparkConf)
val conf = HBaseConfiguration.create()
//conf.set("hbase.zookeeper.quorum","localhost");
//conf.set("hbase.zookeeper.property.clientPort","2181");
//conf.set("zookeeper.znode.parent","/hbase");
conf.set(TableInputFormat.INPUT_TABLE, "resource_usage")
conf.set(TableInputFormat.SCAN_ROW_START, "8111c675d890620dfdc33b792d2152ef_1496080860")
conf.set(TableInputFormat.SCAN_ROW_STOP, "8111c675d890620dfdc33b792d2152ef_1496083860")
val hBaseRDD = sc.newAPIHadoopRDD(conf, classOf[TableInputFormat],
classOf[org.apache.hadoop.hbase.io.ImmutableBytesWritable],
classOf[org.apache.hadoop.hbase.client.Result])
val count = hBaseRDD.count()
println(s"RDD COUNT: $count")
sc.stop()
}
}
Je reçois toujours cette exception:

Je l'ai vu cette question encore une fois mentionné, mais je ne pouvais pas le résoudre en ajoutant $ {} HBase_Home/conf à HADOOP_CLASSPATH.
export HADOOP_CLASSPATH = HADOOP_CLASSPATH de $: $ {} HBase_Home/conf/
