Hi, I start an Hbase cluster for my test class. I use that helper class:
https://github.com/apache/gora/blob/master/gora-hbase/src/test/java/org/apache/gora/hbase/util/HBaseClusterSingleton.java and use it as like that: private static final HBaseClusterSingleton cluster = HBaseClusterSingleton.build(1); I retrieve configuration object as follows: cluster.getConf() and I use it at Spark as follows: sparkContext.newAPIHadoopRDD(conf, MyInputFormat.class, clazzK, clazzV); When I run my test there is no need to startup an Hbase cluster because Spark will connect to my dummy cluster. However when I run my test method it throws an error: 2015-08-26 01:19:59,558 INFO [Executor task launch worker-0-SendThread(localhost:2181)] zookeeper.ClientCnxn (ClientCnxn.java:logStartConnect(966)) - Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error) 2015-08-26 01:19:59,559 WARN [Executor task launch worker-0-SendThread(localhost:2181)] zookeeper.ClientCnxn (ClientCnxn.java:run(1089)) - Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect java.net.ConnectException: Connection refused at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:739) at org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:350) at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1068) Hbase tests, which do not run on Spark, works well. When I check the logs I see that cluster and Spark is started up correctly: 2015-08-26 01:35:21,791 INFO [main] hdfs.MiniDFSCluster (MiniDFSCluster.java:waitActive(2055)) - Cluster is active 2015-08-26 01:35:40,334 INFO [main] util.Utils (Logging.scala:logInfo(59)) - Successfully started service 'sparkDriver' on port 56941. I realized that when I start up an hbase from command line my test method for Spark connects to it! So, does it means that it doesn't care about the conf I passed to it? Any ideas about how to solve it?
