            Can you fetch schemas from spark databases via jdbc?
            Asked 2022-Mar-24 at 04:26

            I'm trying to connect from an instance A in databricks to another databricks instance B to read its tables and schemas (databases)

            How can I fetch the schemas from instance B using jdbc?

            I was facing the same issue, the show keyword was not recognizable so used alternative methods to get the same. I am using the databricks-sql-connector provided by databricks to query another instance. I am providing a detailed link for reference -

            1. You need to install the connector on the instance
            2. generate access_token to access the cluster
            3. you can get all the hostname and path details on the cluster jdbc/odbc tab.

            There are boolean expressions following each when clauses while expression after case clause is of mismatching type.

            Indeed you don't need an expression following case clause for your aim of current case, then just get rid of that such as



            How to test a Spring CommandLineRunner while I am mocking the connection to an external resources?
            Asked 2022-Feb-10 at 11:57

            I want to test the following class, that is a spring boot with CommandLineRunner, if it receives the flag compaction.manually.triggered = true for specific TaskMode. I suppose that I need to instantiate the whole Spring application runner during the test (based on this answer). However, I don't want to connect to external resources (was in my case). So I think I need to mock it as well.



            Answered 2022-Feb-10 at 11:57

            As @M. Deinum said, it is not necessary to start the Spring context to test what I wanted. I will post the solution here just as a reference. I am also using the system-lambda dependency to catch System.exit(-1).



            Testing significance of Strauss parameters in mppm model
            Asked 2022-Jan-03 at 01:13

            I have a follow up question from my previous post.

            Upon creating mppm models like these:



            Answered 2022-Jan-03 at 01:13

            First let me explain that, for Gibbs models, the likelihood is intractable, so anova.mppm performs the adjusted composite likelihood ratio test, not the likelihood ratio test. However, you can essentially treat this as if it were the likelihood ratio test based on deviance differences.

            1. whether each individual id shows significant regularity

            I am aware I could build separate ppm models for each id to test for significant regularity in each id, but I am not sure this is the best approach.

            This is appropriate. Use ppm to fit a Strauss model to an individual point pattern, and use anova.ppm to test whether the Strauss interaction is statistically significant.

            1. whether some groups of ids show significantly stronger inhibition than other groups, for example, whether ids 1-7 are are significantly more regular than ids 8-10.

            Introduce a new categorical variable (factor) f, say, that separates the two groups that you want to compare. In your model, add the term f:str to the interaction formula; this gives you the alternative hypothesis. The null and alternative models are identical except that the alternative includes the term f:str in the interaction formula. Now apply anova.mppm. Like all analyses of variance, this performs a two-sided test. For the one-sided test, inspect the sign of the coefficient of f:str in the fitted alternative model. If it has the sign that you wanted, report it as significant at the same p-value. Otherwise, report it as non-significant.

            1. perform pairwise comparisons of regularity between different ids.

            This is not yet supported (in theory or in software).

            [Congratulations, you have reached the boundary of existing methodology!]



            Connector NoSuchMethodError with complex query
            Asked 2021-Dec-16 at 14:52

            NoSuchMethodErrorUsing the Simba connector, the following query gives me the error below. The query worked fine in the web console tool thingie. All the jar files seem to be there. I updated the JDBC driver version to the latest and get the same error. I turned on logging and it looks like it's about ready to return the results to me before it crashes.



            Answered 2021-Dec-16 at 14:52

            So it looks like the issue was caused byt the fact that I didn't have a limit or provide LargeResultDataset and LargeResultTable parameters. I hope someone finds this useful since this is a very misleading error that nobody has documented.



            maven repository with BigQuery Simba JDBC Connector
            Asked 2021-Dec-15 at 14:11

            I'm starting new backend application that will operate on BigQuery.
            Would love to check Simba JDBC Connector, but my main blocker is no Maven repository with it. It complicates startup significantly.
            Does it always have to be downloaded installed manually or are there any active repositories with it?

            Ps. I'm aware that I cloud run my own nexus repository and deploy it there, but want to avoid it :)



            Answered 2021-Dec-15 at 14:11

            Simba JDBC connector for BigQuery does not have a Maven repository. The jar files need to be downloaded manually right now.There is an ongoing feature request that is being worked on. However, we cannot provide an exact ETA on when that feature will be available.

            You can fix this by adding S3 bucket permission in the QuickSight console.

            Go to:

            Manage QuickSight -> Security & permissions -> Add or remove -> In S3 -> Details -> Select the bucket you want to query -> Update

            Asked 2021-Oct-14 at 17:51

            I was attempting to get the Databricks ODBC driver working on Golang. I followed the directions on in order to setup the Go library and the system library.

            Instead of setting up the MSSQL ODBC driver, I installed Databricks' ODBC driver and configured the system to use it. I re-used a the mssql_test.go file to create a testbed to test the connection to Databricks, using a DSN/connection string I built using the guide from their website.

            However, when attempting to connect to the database, I get the error:

            In this case, the reason that the file cannot be found is that the driver has not been compiled for ARM. This post on Github illustrates the issue.

            We can confirm by running file on the library. It yields...

            Answered 2021-Sep-30 at 19:06

            Dot notation works only for columns types as struct<…>. You can do that for JSON data, but judging from the error and your description this seems not to be the case. I assume your column is of type string.

            If you have JSON data in a string column you can use JSON functions to parse and extract parts of them with JSONPath.



            How to pass arguments in kubernetes to start a rq-worker container

            You do not need the /bin/sh -c wrapper here. Your setup reads the first args: word, rqworker, and parses it as a shell command, and executes it; the remaining words are lost.

            The most straightforward thing to do is to make your command, split into words as-is, as the Kubernetes command:
