Is there any option for Creation of Protobuf schema from JSON Schema classes without using annotaitons for infinispan cache in quakrus
You can do it, but it's not the recommended way of Quarkus. You can disable the schema upload in the server (quarkus.infinispan-client.use-schema-registration=false), do it from your side using the hotrod client, cli, rest, the console...
on the client side you can add a marshaller yourself https://quarkus.io/guides/infinispan-client#custom-serialization

i upgraded my spring boot application to master pom 2.4 version and using cloud configs with the property enabled spring.cloud.bootstrap.enabled = true, I have db password encrypted in cloud properties so by the time i use the db properties i don't have my encryption framework available, so eventually my application failing with invalid username and password .."i have my own encryption service "
i am looking to see load the cloud config properties after i have my encryption service available, but the spring.cloud.bootstrap.enabled makes it load first on application startup, before i upgrade to master pom, i was not using spring.cloud.bootstrap.enabled so i didn't had any issue, with adding the property the order of loading changed, so i am running into an issue. Any help will be greatly appreciated. Thanks
so by the time i use the db properties i don't have my encryption
framework available
Use #DependsOn annotation in the bean that uses the db properties to depend on the encryption framework.
I am performing XML to JSON transformations using Transform Message connector. I have created a mule-plugin for the transformations code and added it as a dependency to my application. When I deploy the application in anypoint studio(4.3.0) it is working as expected i.e. I am getting the full payload transformed to JSON. But, when I deploy the same application to ONPREM some fields of input(XML) are missing in the output(JSON). In case of the ONPREM application I am sending the message(XML-payload) via JMS(1.7.1)-Publish by publishing it to a JMS queue where my application is listening using JMS-On New Message and using the transformations mule-plugin(added as a dependency) to transform the XML to JSON and publishing via JMS-publish to a queue where another API is listening.
I observed that when I am dividing parts of dwl in modules and importing them in a main dwl and deploying at ONPREM the fields are missing. But, when I am using all the module's dwl code in same dwl file I am getting all the fields.
Please Help me with this.
Issue Resolved. There was a difference between Studio Runtime and ONPREM Runtime. When I patched the ONPREM with latest update. The Issue got Resolved.
I am using R2DBC-H2 driver, and my UR.L is spring.r2dbc.url=r2dbc:h2:mem:///customer
Using this configuration, SpringBoot starts fine, however, I can not access the h2-console.
Does anybody know why, and how I can fix it?
If I understand the source code of H2ConsoleAutoConfiguration correctly, the h2 console auto configuration from spring boot does not work in a reactive environment.
...
#ConditionalOnWebApplication(type = Type.SERVLET)
...
public class H2ConsoleAutoConfiguration {
You can confirm this by yourself by changing the type of your web application to SERVLET (for example, by adding spring-boot-starter-web as a dependency) which will activate the route to the h2 console (if enabled in the application properties). The h2-console route endpoint will start working again.
As the whole code seems very servlet-specific, I don't know how to properly fix this problem.
H2 Console depends on traditional Jdbc drivers, not compatible with Spring WebFlux stack.
If you are developing a WebFlux application, you can use H2 as a standalone database, ane use H2 Console freely.
Following the official Getting Started guide to start H2 Database and H2 Console.
Set your spring.r2dbc.url to the database url you are running in the first step.
NOTE: Do not use a Memory DB here.
I want connect my BoondManager ERP with Talend. I need to Extact the Database of Boond.
I tried to use WSDL file.but i couldn't retrieve the schema
I wanna really just establish the connection between the Boond Aplication and talend to extract Data. Can i find someone who has already worked on that ?
You'll need a tESBConsumer component to connect to your application through SOAP . Just give the WSDL address or file, and in the service configuration popup, select 'populate schema to repository on finish' to get your request/response schema, that you'll be able to use with tXMLMap before and after your tESBConsumer
Currently I am having an issue really need some help.
We are trying kerberize our hadoop cluster including hive server2 and oozie. My oozie job spins off a java action in data node which tries to connect to kerberized hive server 2.
There is no user’s kerberos keytab for authentication. So I can only use delegation token passed by oozie in the java action to connect to hive server 2.
My question is: is there any way that I can use delegation token in a oozie java action to connect to hive server 2? If so, how can I do it through hive JDBC?
Thanks
Jary
When using Oozie in a kerberized cluster...
for a "Hive" or "Pig" Action, you must configure <credentials> of
type HCat
for a "Hive2" Action (just released with V4.2) you must configure
<credentials> of type Hive2
for a "Java" action opening a custom JDBC connection to HiveServer2,
I fear that Oozie cannot help -- unless there is an undocumented hack that would make it possible to reuse this new Hive2 credential?!?
Reference: Oozie documentation about Kerberos credentials
AFAIK you cannot use Hadoop delegation tokens with HiveServer2. HS2 uses Thrift for managing client connections, and Thrift supports Kerberos; but the Hadoop delegation tokens are something different (Kerberos was never intended for distributed computing, a workaround was needed)
What you can do is ship a full set of GSSAPI configuration, including a keytab, in your "Java" Action. It works, but there are a number of caveats:
the Hadoop Auth library seems to be hard-wired on the local ticket
cache in a very lame way; if you must connect to both HDFS and
HiveServer2, then do HDFS first, because as soon as JDBC initiates
its own ticket based on your custom conf, the Hadoop Auth will be broken
Kerberos configuration is tricky, GSSAPI config is worse, and since
these are security features the error messages are not very
helpful, by design (would be bad taste to tell hackers why their intrusion
attempt was rejected)
use OpenJDK if possible; by default the Sun/Oracle JVM has
limitations on cryptography (because of silly and obsolete US
exports policies) so you must download 2 JARs with "unlimited
strength" crypto settings to replace the default ones
Reference: another StackOverflow post that I found really helpful to set up "raw" Kerberos authentication when connecting to HiveServer2; plus a link about a very helpful "trace flag" for debugging your GSSAPI config e.g.
-Djava.security.debug=gssloginconfig,configfile,configparser,logincontext
Final warning: Kerberos is black magic. It will suck your soul away. More prosaically, it will have you lose many man-days to cryptic config issues, and team morale will suffer. We've been there.
Like Samson said Java action in Oozie requires additional authentication to connect to some "kerberized" services like hive. It can be achieved in a relativly simple way, without modifications in application.
