I tried to setup a local druid cluster and load batch data into historical nodes
I followed the instructions as in http://druid.io/docs/latest/tutorials/tutorial-loading-batch-data.html.
According to http://druid.io/docs/latest/misc/tasks.html the index task is a variation that does not require external hadoop set up.
When I post the task for indexing, it fails with the following error in the logs.
I tried 4 different ways of staring the indexer [the instructions mention to include the “<hadoop_config_path>” at the end of the classpath]
- Omitting hadoop-config path altogether when starting the indexer
- Point to a local hadoop install (not running) top-level directory
- Point to the local install’s config directory (with nothing running)
- Specfically add hadoop-common-2.3.0.jar to the class path
All of these result in the same error. What am I doing wrong?
