Spark 1.4.1 and HBase 1.1.2 Integration

vjain — Tue, 12 Jan 2016 04:38:37 GMT

I am running the following:

$ run-example HBase-table <tablename>

But I keep getting the following error message:

I have tried with adding the hbase-<version>-client.jar to both Hadoop & Spark classpath but to no avail.

@Vedant Jain

You have to set hbase jar in Hadoop Class path.

Hi Neeraj, I did not mention it .. but I tried $HADOOP_CLASSPATH as well as $SPARK_CLASSPATH. It did not work.

Have you tried on HDP 2.3.4? Not sure if its related but there was an issues with phoenix-spark connector in previous minor versions of 2.3 versions due to PHOENIX-2040 being missed (here is the internal jira)

@Vedant Jain

Looking at this example...I am not sure if you did export hbase xml file

I think this should make it work:

export SPARK_CLASSPATH=/usr/lib/hbase/lib/hbaseprotocol.jar:/etc/hbase/conf:$(hbase classpath) or you add the HBase dependency with this: --driver-class-path hbase-dependency at the spark-submit.
