I am trying to setup Apache Hudi on an Ubuntu 16.04 server. I cloned the repo https://github.com/apache/incubator-hudi.git and then build it as 

mvn clean install -DskipTests -DskipITs

The build completed successfully.

I then proceeded with testing by following through https://hudi.incubator.apache.org/docker_demo.html

When I try to execute 

spark-submit --class com.uber.hoodie.utilities.deltastreamer.HoodieDeltaStreamer $HUDI_UTILITIES_BUNDLE --storage-type COPY_ON_WRITE --source-class com.uber.hoodie.utilities.sources.JsonKafkaSource --source-ordering-field ts  --target-base-path /user/hive/warehouse/stock_ticks_cow --target-table stock_ticks_cow --props /var/demo/config/kafka-source.properties --schemaprovider-class com.uber.hoodie.utilities.schema.FilebasedSchemaProvider

I get the output 

...

Due to insufficient reputation I could not add incubator-hudi tag to the question.
Thanks for help

  • which hudi version are you using? can you try with https://github.com/apache/incubator-hudi/archive/hoodie-0.4.7.zip ? – jaimin03 Jun 26 '19 at 11:55
  • @jaimin03 I am using the latest version obtained by cloning the github repo I previously tried the version 0.4.7 and this issue did not arise in that version and I successfully executed the first 7 steps in https://hudi.apache.org/docker_demo.html. However, when I tried to execute the Step 8 (https://hudi.apache.org/docker_demo.html#step-8-schedule-and-run-compaction-for-merge-on-read-dataset) , trying to execute 'connect --path /user/hive/warehouse/stock_ticks_mor' resulted in error that there was no such command. So I went for the latest version. – Nadeem Mehraj Jun 27 '19 at 10:48
