Subject Frequently unable to make a JDBC connection oadd.org.apache.drill.exec.rpc.RpcException: Future failed
Date Mon, 08 Feb 2016 14:16:31 GMT
Have installed Apache Drill 1.4.0 onto two Windows 2012 server (A)  and
Windows 2008 R2 server(B).
Drill bit running on (A) and (B)
Zookeeper running on (B)
Drill browser UI shows both bits as initialized etc

Am able to use SQLSquirrel 3.7 on machine (A) where the URL references
zookeeper on (B)
Am unable to use SQLSquirrel on machine (B) using the same URL

Unable to make connections from other machines (Windows 7 Pro) in the
network using SQLSquirrel or simple program
Have explicitly defined firewall rules on both (A) and (B) for the ports
Drill uses

Simple Java programs can also experience similar problems where the
following exception is thrown and the program is blocked.

Similar problem trying to use a URL to a drillbit versus zookeeper style of
URL.


zookeeper style URL fails as shown
