Trying bulk load using Hfiles in Spark as below example:
import org.apache.spark._
import org.apache.spark.rdd.NewHadoopRDD
import org.apache.hadoop.hbase.{HBaseConfiguration, HTableDescriptor}
import org.apache.hadoop.hbase.client.HBaseAdmin
import org.apache.hadoop.hbase.mapreduce.TableInputFormat
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.hbase.HColumnDescriptor
import org.apache.hadoop.hbase.util.Bytes
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.mapred.TableOutputFormat
import org.apache.hadoop.mapred.JobConf
import org.apache.hadoop.hbase.io.ImmutableBytesWritable
import org.apache.hadoop.mapreduce.Job
import org.apache.hadoop.mapreduce.lib.input.FileInputFormat
import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat
import org.apache.hadoop.hbase.KeyValue
import org.apache.hadoop.hbase.mapreduce.HFileOutputFormat
import org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles
So far no issues.
Then I do
val conf = HBaseConfiguration.create()
conf: org.apache.hadoop.conf.Configuration = Configuration:
core-default.xml, core-site.xml, mapred-default.xml, mapred-site.xml,
yarn-default.xml, yarn-site.xml, hbase-default.xml, hbase-site.xml
val tableName = "testTable"
tableName: String = testTable
But this one fails:
scala> val table = new HTable(conf, tableName)
java.io.IOException: java.lang.reflect.InvocationTargetException

I have got all the jar files in spark-defaults.conf
spark.driver.extraClassPath
/home/hduser/jars/ojdbc6.jar:/home/hduser/jars/jconn4.jar:/home/hduser/jars/hbase-client-1.2.3.jar:/home/hduser/jars/hbase-server-1.2.3.jar:/home/hduser/jars/hbase-common-1.2.3.jar:/home/hduser/jars/hbase-protocol-1.2.3.jar:/home/hduser/jars/htrace-core-3.0.4.jar:/home/hduser/jars/hive-hbase-handler-2.1.0.jar
spark.executor.extraClassPath

and also in Spark shell where I test the code
--jars
/home/hduser/jars/hbase-client-1.2.3.jar,/home/hduser/jars/hbase-server-1.2.3.jar,/home/hduser/jars/hbase-common-1.2.3.jar,/home/hduser/jars/hbase-protocol-1.2.3.jar,/home/hduser/jars/htrace-core-3.0.4.jar,/home/hduser/jars/hive-hbase-handler-2.1.0.jar'
So any ideas will be appreciated.
Thanks
