Hi,
I used below code to insert data from Spark1.5.2 to Phoenix 4.4
df.write.format("org.apache.phoenix.spark").mode(SaveMode.Overwrite).options(collection.immutable.Map(
"zkUrl" -> "localhost:2181/hbase-unsecure",
"table" -> "TEST")).save();
Spark job run parameters
spark-shell --properties-file /TestDivya/Spark/Phoenix.properties --jars /usr/hdp/2.3.4.0-3485/phoenix/lib/phoenix-spark-4.4.0.2.3.4.0-3485.jar,/usr/hdp/2.3.4.0-3485/phoenix/phoenix-client.jar --driver-class-path /usr/hdp/2.3.4.0-3485/phoenix/lib/phoenix-spark-4.4.0.2.3.4.0-3485.jar,/usr/hdp/2.3.4.0-3485/hbase/lib/phoenix-client-4.4.0.jar --conf "spark.executor.extraClassPath=/usr/hdp/2.3.4.0-3485/phoenix/lib/phoenix-core-4.4.0.2.3.4.0-3485.jar" --conf "spark.executor.extraClassPath=/usr/hdp/2.3.4.0-3485/phoenix/lib/phoenix-core-4.4.0.2.3.4.0-3485.jar" --packages com.databricks:spark-csv_2.10:1.4.0 --master yarn-client -i /TestDivya/Spark/WriteToPheonix.scala
I am getting below error when I am running the spark job
org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 3.0 failed 4 times, most recent failure: Lost task 0.3 in stage 3.0 (TID 411, ip-xxxxx-xx-xxx.ap-southeast-1.compute.internal): java.lang.RuntimeException: java.sql.SQLException: No suitable driver found for jdbc:phoenix:localhost:2181:/hbase-unsecure;

Hi, I have registered the hive external table on hbase table. When I try to access that through hiveContext getting below error org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in sta ge 0.0 failed 4 times, most recent failure: Lost task 0.3 in stage 0.0 (TID 3, i p-172-31-29-201.ap-southeast-1.compute.internal): java.lang.RuntimeException: hb ase-default.xml file seems to be for an older version of HBase (null), this vers ion is 1.1.2.2.3.4.0-3485
at org.apache.hadoop.hbase.HBaseConfiguration.checkDefaultsVersion(HBase Configuration.java:71)
at org.apache.hadoop.hbase.HBaseConfiguration.addHbaseResources(HBaseCon figuration.java:81) I have already placed hbase-default.xml ,hbase-site.xml in spark/conf by setting the below property to true <property>
<name>hbase.defaults.for.version.skip</name>
<value>true</value>
<description>Set to true to skip the 'hbase.defaults.for.version' check.
Setting this to true can be useful in contexts other than
the other side of a maven generation; i.e. running in an
IDE. You'll want to set this boolean to true to avoid
seeing the RuntimeException complaint: "hbase-default.xml file

version is X.X.X-SNAPSHOT"</description>

Hi, Would really appreciate if somebody can give me pointers how can I store the pig output using DBStorage to Oracle. Below is my sample script : REGISTER /TestDivya/Pig/ojdbc6.jar ;
REGISTER /TestDivya/Pig/piggybank-0.15.0.jar ;
A = LOAD '/tmp/TestDivya/Pig/PigTest.txt' using PigStorage(',') as (name: chararray, age: int);
STORE A into 'dummy' using org.apache.pig.piggybank.storage.DBStorage('oracle.jdbc.driver.OracleDriver','jdbc:oracle:thin:@xx.xxx.xxx.xx:1521:db_name','db_username','db_password','insert into TEST values(?,?)');

Hi, HDP 2.3.2 cluster is set up on EC2 . When try to view the application logs for particular job it says " web page is not available" the application job url is mapped to internal IP rather than external . When try to view the logs of the application as its is mapped to internal IP . How can I map application logs to external IPs . P.S. - Using elastic IP (EC2) for the name node . Thanks, Divya
