QUESTION

How to determine which Apache Drill drillbit was selected when connecting via zookeeper?

Asked 2021-Jul-01 at 21:09

I'm using a zookeeper connection string to get a connection to a drill cluster. I would like to log which drillbit (hostname or IP address) I successfully connected to, but I can't find any property or method on the java.sql.Connection class to get this information.

I tried connection.getMetaData.getURL, but that just returns the zookeeper connection string I used to get the connection (scala code below):

Don’t forget that you can ask these questions directly to the Apache Drill community on the drill mailing lists or slack channels. See https://drill.apache.org/community-resources/ for more details.

Specific to your question, check out the system tables (https://drill.apache.org/docs/querying-system-tables/). The sys.profiles_json table, in particular, seems to be the one that is likely to give you the information you need.

It is a generally pretty safe bet that if you can see the information that you need in the web interface for Drill that you will also be able to find that information in the system tables. Commonly, a quick scan of the docs and some trial queries will give you the info you need. Since the web interface is open source, you can also grovel the source code to figure out how the web interface gives you the pertinent info.

In particular, this query gives roughly what you are asking for:

Python: JDBC Connection Error to Apache Drill Error with JayDeBeApi

Asked 2020-Oct-07 at 08:43

I am trying to connect to Apache Drill from python using jaydebeapi library.

I have turned on drill in embedded mode via drill-embedded, and the web ui runs correctly in port 8047. Then, I am trying to connect via JDBC through a python script:

Thanks to @Luke Woodward suggestion, the problem was the port. For drill-embedded there is no port to select. Below a full query example

QUESTION

Unable to start Drill in distributed mode

Asked 2020-May-11 at 15:58

I am trying to setup drillv1.18 running. Facing the error below.

The drill-override.conf points to the zookeeper which runs on port 12181. On starting in distributed mode, it fails with the following log output. But the embedded mode has no issues. It appears like permission issue, but both zookeeper, drill, zookeeper data-dir all are running under the same user.

The issue here is with the zookeeper version. Perhaps you use 3.4.X version, but the current version of Drill requires 3.5.X. As a workaround, you may replace zookeeper jar in jars/ext/zookeeper-3.5.7.jar and jars/ext/zookeeper-jute-3.5.7.jar with the jars that corresponds to your zookeeper version.

QUESTION

Heap memory Usage is Not Available on distributed mode in the Drill Web UI

Asked 2020-Mar-10 at 20:28

I installed Drill(1.16 version) on 3 nodes and use distributed mode. Becuz when i implemented query(join multiple table), I want to distribute the memory usage.

But When I enter Drill Web UI, Only a drillbit that I access gives information about usage. other drillbit says Not Available.

I wonder if distributed mode is working well or not.

Just for test, When I implement a query which joins 3 tables on different node(PostgreSQL), only single major fragment is created and performed.(that means single drillbit is working and does not distribute the memory usage)

This is Web UI. you can see the Not available sign.

This is conf/drill-override.conf

This issue was fixed in the scope of https://issues.apache.org/jira/browse/DRILL-7582 and https://issues.apache.org/jira/browse/DRILL-7619, so on the current master version, these metrics should be displayed.

As a workaround for older versions, you may update your /etc/hosts file to map nodes IPs with their hostnames.
