Apache Drill 1.6.0 failure in starting embedded Drillbit (windows) - windows

Question

I am unable to start Embedded drillbit on windows machine and getting the following error. I have checked for the jars in 3rd party folder where Jackson-databind-2.7.1.jar is present, still it's saying class not found exception. Can you help me here?

Answer 1

The issue is related with the HADOOP_HOME environment variable
If it is set, Embedded Drill does not start properly
My HADOOP_HOME was set because I use sometimes Spark or Hadoop MapReduce on my machine.
So, with
set HADOOP_HOME=
and then
sqlline.bat -u "jdbc:drill:zk=local"
The initialization is completed and the Drillbit starts
