What is the error for the collocated Drillbit instance ? Did you apply the "DRILL_HOST_NAME" to the collocated Drillbit's drill-env.sh file as well?
One quick test is to try if the ZK port is accessible locally, but not using the loopback IP (i.e. 127.0.0.1 ). Telnet is a good way to verify that you're able to connect. -----Original Message----- From: Knapp, Michael [mailto:michael.kn...@capitalone.com] Sent: Friday, March 31, 2017 11:41 AM To: user@drill.apache.org Subject: Struggling to run in distributed mode Hi, I am struggling to get drill to run in distributed mode. I stood up two Amazon EC2 instances using amazon’s linux for the OS, on m4.large instances. I decided to install zookeeper on one of them. I also have java 8 installed on each of them. I followed the instructions provided here: https://drill.apache.org/docs/installing-drill-on-the-cluster/ My drill-override.conf file is the same on each node, it looks like this: drill.exec: { cluster-id: "drillbits1", zk.connect: "10.XXX.YYY.ZZZ:2181" } The IP address of the zookeeper is the same as one of the drill nodes, because it is running on the same machine. Unfortunately for me, drillbit.sh fails. On the machine that is co-located with zookeeper, I get this IOException in the drillbit.out file: Failure to connect to the zookeeper cluster service within the allotted time of 10000 milliseconds I have confirmed that ZK is running and I can open a shell to it. On the machine that is NOT co-located with zookeeper, I get a DrillbitStartupException: Drillbit is disallowed to bind to loopback address in distributed mode. I looked in the drillbit.log file, it has: host.name=ip-10-XXX-YYY-ZZZ.****.com. After reviewing the source code, I realized that Drill lets you override the host name from drill-env.sh. By setting “DRILL_HOST_NAME” to the IP address, I was able to start the Drill instance that is NOT co-located with Zookeeper. However, the same solution did not work with the instance that is co-located with zookeeper, it is still failing with a timeout while trying to connect with Zookeeper. I do not understand why this is not working, would somebody please explain what is happening? Also, would somebody please update the installation instructions to explain when I need to set the “DRILL_HOST_NAME”? Last and most importantly, why is my Drill instance unable to connect with Zookeeper on its own machine?
