I think this was due to non runnning metstore service from hive. You should run command "hive --service metastore & " first and then start hive console.

The full format of an HDFS uri is: hdfs://NAMESERVICE/path/to/your/file
hdfs://NAMESERVICE/path/to/your/directory or hdfs://ANYNAMENODE:PORT/path/to/your/file
hdfs://ANYNAMENODE:PORT/path/to/your/directory It is ok to omit the nameservice/namenode part (to use the defaultFs). To do it correctly, you need to keep the `hdfs://` part and relative path that starts with a `/`. That is: hdfs:///path/to/your/file (Note that it looks like `hdfs:` followed by 3x `/`s)

Issue got resolved . Follow this checklists -- 1. Check Zookeeper running . 2. Check Kafka Producer and Consumer running fine on console, create one topic and list it this is to ensure that kafka running fine . 3. Similar version use in sbt like for Kafka 0.9 below should be use : org.apache.flink" %% "flink-connector-kafka-0.9" % flinkVersion % "provided" and import in scala program : import org.apache.flink.streaming.connectors.kafka.{FlinkKafkaProducer09, FlinkKafkaConsumer09} For Kafka 0.10 org.apache.flink" %% "flink-connector-kafka-0.10" % flinkVersion % "provided"
And Import in scala program : import org.apache.flink.streaming.connectors.kafka.{FlinkKafkaProducer10, FlinkKafkaConsumer10}

I got the answer for this question : Number of partitions for a topic can only be increased, never decreased Reason for this as if we decrease the partition it will be data loss . We can delete current topic and recreate new one with required partition to achieve this .

you can set the values for the follwoing attributes. offsets.topic.num.partitions=50 offsets.topic.replication.factor=3 losing this topic may cause issue for kafka broker to startup of service consumer request(metadata fetch failure)

When we run from terminal its running fine . We are getting issue while submitting program from local (using eclipse) and phoenix is in these servers(10.40.17.183,10.40.17.155,10.40.17.129). Can you please validate hbase-site.xml ( Do I need to place this file to hbase/conf and Phoenix/bin for all three servers/nodes) <?xml version="1.0"?>
