Dear all,
I am trying to integrate Hue with Drill (on MapR Sandbox with Drill) and I
encountered the following problem.
An error occurred while calling z:java.sql.DriverManager.getConnection. :
java.lang.IllegalStateException: No active Drillbit endpoint found from
ZooKeeper. Check connection parameters? at

java.lang.Thread.run(Thread.java:748)
I have checked the drill-override.conf, which looks as following:
drill.exec: {
cluster-id: "demo_mapr_com-drillbits",
zk.connect: "maprdemo:5181"
hbase.scan.sizecalculator.enabled: "false"
}
And I added drill as interpreter:
[[[drill]]]
name=Drill JDBC
interface=jdbc
## Specific options for connecting to the server.
## The JDBC connectors, e.g. mysql.jar, need to be in the CLASSPATH
environment variable.
## If 'user' and 'password' are omitted, they will be prompted in the UI.
options='{"url": "jdbc:drill:zk=maprdemo:5181", "driver":
"org.apache.drill.jdbc.Driver", "user": "mapr", "password": "mapr"}'
and also defined the dbproxy_extra_classpath.
Do you have any ideas what the problem is?
Thank you in advance!
Best
Karolina
