Hi,
First attempt with Apache Drill, and failing spectacularly to get off the
ground with it...
Downloaded and unpacked apache-drill-1.6.0.tar.gz on my Oracle Linux 6 VM.
Followed the "Drill in 10 Minutes" (
https://drill.apache.org/docs/drill-in-10-minutes/) tutorial.
But, I'm stuck at "No current connection", whatever I do.
Session output:
----
[oracle@bigdatalite opt]$ cd apache-drill-1.6.0/
[oracle@bigdatalite apache-drill-1.6.0]$ ./bin/drill-embedded
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option
MaxPermSize=512M; support was removed in 8.0

"the only truly happy people are children, the creative minority and drill
users"
0: jdbc:drill:zk=local> SELECT version FROM sys.version;
No current connection
0: jdbc:drill:zk=local>
----
In hacking around trying to get this to work, I also tried drillbit:
---
[oracle@bigdatalite bin]$ ./drillbit.sh start
starting drillbit, logging to /opt/apache-drill-1.6.0/log/drillbit.out
---
and the drillbit.out shows that this fails, with a class error:
---
Exception in thread "main" java.lang.NoSuchMethodError:

I don't know if this error is related to the problem I'm seeing when trying
to run it embedded, but I'm stuck -- pointers for help would be welcome!
thanks, Robin.
