When running in clustered mode you ZK running and point to it appropriately.
It seems you don't have ZK running in your environment. You can however connect multiple session to Drill in embedded mode. Simply point directly to the drillbit as apposed to using ZK. I.e. Start Drill with drill-embedded this will open a sqlline session. From anther terminal window you can then run ./sqlline -u jdbc:drill:drillbit=localhost if its is on the same machine, or just point to the hostname from another machine. If you use ODBC or JDBC the drillbit is on port 31010 for client connections by default. --Andries > On Feb 22, 2016, at 8:33 AM, Ted Schwartz <[email protected]> wrote: > > I'm new to drill and trying to get up and running.
