Hi, there
You may want to check your hbase config.
e.g. the following property can be changed to /hbase
<property>
<name>zookeeper.znode.parent</name>
<value>/hbase-unsecure</value>
</property>

Subject: Problem connecting to HBase
Hello,
I am running a HBase test case. I am using the example from the following:
https://github.com/apache/spark/blob/master/examples/src/main/scala/org/apache/spark/examples/HBaseTest.scala
I created a very small HBase table with 5 rows and 2 columns.
I have attached a screenshot of the error log. I believe it is a problem where
the driver program is unable to establish connection to the hbase.
The following is my simple.sbt:
name := "Simple Project"
version := "1.0"
scalaVersion := "2.10.4"
libraryDependencies ++= Seq(
"org.apache.spark" %% "spark-core" % "1.2.0",
"org.apache.hbase" % "hbase" % "0.98.9-hadoop2" % "provided",
"org.apache.hbase" % "hbase-client" % "0.98.9-hadoop2" % "provided",
"org.apache.hbase" % "hbase-server" % "0.98.9-hadoop2" % "provided",
"org.apache.hbase" % "hbase-common" % "0.98.9-hadoop2" % "provided"
)
I am using a 23 node cluster, did copy hbase-site.xml into /spark/conf folder
and set spark.executor.extraClassPath pointing to the /hbase/ folder in the
spark-defaults.conf
Also, while submitting the spark job I am including the required jars :
spark-submit --class "HBaseTest" --master yarn-cluster --driver-class-path
/opt/hbase/0.98.9/lib/hbase-server-0.98.9-hadoop2.jar:/opt/hbase/0.98.9/lib/hbase-protocol-0.98.9-hadoop2.jar:/opt/hbase/0.98.9/lib/hbase-hadoop2-compat-0.98.9-hadoop2.jar:/opt/hbase/0.98.9/lib/hbase-client-0.98.9-hadoop2.jar:/opt/hbase/0.98.9/lib/hbase-common-0.98.9-hadoop2.jar:/opt/hbase/0.98.9/lib/htrace-core-2.04.jar
/home/priya/usingHBase/Spark/target/scala-2.10/simple-project_2.10-1.0.jar
/Priya/sparkhbase-test1
It would be great if you could point where I am going wrong, and what could be
done to correct it.
Thank you for your time.
