Subject Hortonworks Spark-Hbase-Connector does not read zookeeper configurations from spark session config ??(Spark on Yarn)
Date Thu, 22 Feb 2018 08:04:16 GMT
Hi

I am trying to write a spark code that reads data from Hbase and store it
in DataFrame.
I am able to run it perfectly with hbase-site.xml in $spark-home/conf
folder.
But I am facing few issues Here.

Issue 1: Passing hbase-site.xml location with --file parameter submitted
through client mode(It is working in cluster mode)

When I  removed hbase-site.xml from spark/conf and try to execute it in the
client mode by passing with file --file parameter over yarn I keep getting
the following exception. Which I think it means it is not taking the
zookeeper configuration from hbase-site.xml. How ever it works good when
i run it in cluster mode.
sample command

spark-submit --master yarn --deploy-mode cluster --files
/home/siddesh/hbase-site.xml --class com.orzota.rs.json.HbaseConnector
 --packages com.hortonworks:shc:1.0.0-2.0-s_2.11 --repositories
http://repo.hortonworks.com/content/groups/public/
target/scala-2.11/test-0.1-SNAPSHOT.jar

Issue 2: Passing hbase configuration details through spark session(Not
working in cluster as well as client mode).
Instead of passing the entire hbase-site.xml I am trying to add the
configuration directly in the spark code by adding it as a config parameter
in spark session the following is a sample spark-session command.

val spark = SparkSession
                                        .builder()
                                        .appName(name)

.config("hbase.zookeeper.property.clientPort", "2181")
                                        .config("hbase.zookeeper.quorum",
"ip1,ip2,ip3")

.config("spark.hbase.host","zookeeperquorum")
                                        .getOrCreate()

val json_df =
spark.read.option("catalog",catalog_read).format("org.apache.spark.sql.execution.datasources.hbase").load()

But it is not working in the cluster mode while the issue-1 continues in
the client mode.

Can anyone help me with a solution or explanation why this is happening are
there any work arounds ??.

regards
Sid
