Subject Problem connecting to HBase
Date Fri, 13 Mar 2015 19:18:24 GMT
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.
