Using Apache Drill v1.2 and Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit in embedded mode. I'm curious if anyone has had any success connecting Apache Drill to an Oracle DB. I've updated the drill-override.conf with the following configurations (per documents): drill.exec: { cluster-id: "drillbits1", zk.connect: "localhost:2181", drill.exec.sys.store.provider.local.path = "/mypath" } and placed the ojdbc6.jar in \apache-drill-1.2.0\jars\3rdparty . I can successfully create the storage plug-in: { "type": "jdbc", "driver": "oracle.jdbc.driver.OracleDriver", "url": "jdbc

I downloaded Apache Drill v1.8, edited the conf/drill-override.conf to have the following changes: drill.exec: { cluster-id: "drillbits1", zk.connect: "10.178.23.140:2181,10.178.23.140:2182,10.178.23.140:2183,10.178.23.140:2184" } ..zookeeper cluster is effectively consisted of 4 Zookeeper instances started on the same, one machine, I'm trying to start Drill on. (i.e. I'm only using one machine for Apache Drill and Zookeeper's cluster, the machine's IP is 10.178.23.140 ) So I keep getting this error: Exception in thread "main" org.apache.drill.exec.exception.DrillbitStartupException: Failure

I have my data in a propriety format, None of the ones supported by Apache drill. Are there any tutorial on how to write my own storage plugin to handle such data. This is something that really should be in the docs but currently is not. The interface isn't too complicated, but it can be a bit much to look at one of the existing plugins and understand everything that is going on. There are 2 major components to writing a storage plugin, exposing information to the query planner and schema management system and then actually implementing the translation from the datasource API to the drill

Throughout the Wiki of Apache Drill, I could only see queries running via SqlLine client. Is there any programmatical way to run queries in Drill other than the REST API? Any samples or pointers? Or is it as equivalent as using JDBC driver to run SQL queries? You can use the Drill JDBC driver, which is documented here: http://drill.apache.org/docs/using-the-jdbc-driver/ Note that if you're building your Java program with Maven, you'll need to install the Drill dependencies locally: mvn install:install-file -Dfile=/opt/apache-drill-1.0.0/jars/drill-java-exec-1.0.0-rebuffed.jar -DgroupId=org

I've been hunting around for a solution to this question. It appears to me that there is no way to embed reading and writing Parquet format in a Java program without pulling in dependencies on HDFS and Hadoop. Is this correct? I want to read and write on a client machine, outside of a Hadoop cluster. I started to get excited about Apache Drill, but it appears that it must run as a separate process. What I need is an in-process ability to read and write a file using the Parquet format. Krishas You can write parquet format out side hadoop cluster using java Parquet Client API. Here is a sample
