The node /hbase is not in ZooKeeper. It should have been written by the master

biswajit_kundu — Fri, 08 Apr 2016 19:54:18 GMT

Hi,

I'm trying to write to Phoenix from Spark. But I'm getting exception saying

"ERROR org.apache.hadoop.hbase.client.ConnectionManager$HConnectionImplementation - The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master."

Environment Info:

Hadoop Environment: HDP 2.3.4

HBase Version : 1.1.2

Phoenix Version : 4.4.0

After installing phoenix I have executed "./psql.py zookeeperhost1,zookeeperhost2,zookeeperhost3:2181 ~/phoenix/us_population.sql ~/phoenix/us_population.csv ~/phoenix/us_population_queries.sql" and this worked fine

Here is my Spark Code:

import org.apache.spark._
import org.apache.spark.SparkContext
import org.apache.phoenix.spark._
object PhoenixSample {
   def main(args: Array[String]) {
    val conf = new SparkConf().setMaster(args(0)).setAppName(args(1))
    //conf.set("zookeeper.znode.parent", "/hbase-unsecure") //Tried this as well, same error.
    val sc = new SparkContext(conf)
    
    val dataSet = List(("MI", "Holland", 100), ("MI", "Detroit", 200), ("MI", "Cleave Land", 300))
    sc
    .parallelize(dataSet)
        .saveToPhoenix(
                args(2),
                Seq("STATE","CITY","POPULATION"),
                zkUrl = Some(args(3))
        )
   }
}

Hi,

Missed to add the spark submit command I used. Here it goes

Re: The node /hbase is not in ZooKeeper. It should have been written by the master

bleonhardi — Fri, 08 Apr 2016 20:39:02 GMT

In an unkerberised HDP cluster the hbase node is

/hbase-unsecure

and will be changed to

/hbase-secure

In this question he did the same thing and fixed it by adding the url

"zkUrl","sandbox:2181:/hbase-unsecure",

https://community.hortonworks.com/questions/18228/phoenix-hbase-problem-with-hdp-234-and-java.html

I doubt adding it to the spark config helps anything ( only parameters with spark. get serialized for example )

sqlline needed the /hbae-unsecure before but in the newest version they seem to take the znode from the hbase-site.xml if not otherwise configured.

You can check in your hbase-site which node is needed.
