We are using HDP 3.1.4 and want to use kafka-handler for Kafka and Hive integration.
Lots of our topics in Kafka are serialized with Avro using Confluent Schema Registry and the default kafka-handler shipped with HDP 3.1.4 does not contain new features for Avro messages serialized with Confluent that contains Magic Byte. in new versions of kafka-handler we have some properties such as 'avro.serde.type'='skip' and 'avro.serde.skip.bytes'='5' to handle Magic Byte.
So we wanted to replace kafka-handler with our own compiled kafka-handler 4.0.
we simply started with replacing kafka-handler 4.0 with default HDP kafka-handler but we faced this error :
MetaException(message:java.lang.NoSuchFieldError AVRO_SERDE_TYPE)
AVRO_SERDE_TYPE is added in hive-serde 4.0 and we investigate it is because kafka-handler has dependency to kafka-exec and kafka-exec contains our old hive-serde that shipped with HDP.
We should replace hive-serde too. so we continue with shading hive-serde in kafka-handler:
<relocation>
<pattern>org.apache.hadoop.hive.serde2</pattern>
<shadedPattern>org.shaded.apache.hadoop.hive.serde2_shaded</shadedPattern>
</relocation>
but we face this exception:
SQL Error [40000] [42000]: Error while compiling
statement: FAILED: ClassCastException class org.apache.hadoop.hive.kafka.KafkaSerDe
so how we should handle this issue ?

I have checked with axis2 1.4.1 version , there is no issue found , And for upgrading axis version same code has done with latest version 1.7.7
In 1.4.1 version it was successful,
contentType:Before:multipart/related; boundary="----=_Part_3837_17859151.1531477242209"
contentType:After:multipart/related; boundary="----=_Part_3837_17859151.1531477242209"; type="text/xml"
The type is getting as type="text/xml" while using axis2 1.4.1
but in axis2 1.7.7 , when i checked it is found that the content type is null . so null pointer exception is coming . i want to know why the type is getting as null
contentType:Before:multipart/related; boundary="----=_Part_3837_17859151.1531477242209"
contentType:After:multipart/related; boundary="----=_Part_3837_17859151.1531477242209";
please help me.
Backward incompatible changes as described in Axis2 1.7.0 release notes:
Apache Axis2 1.7.0 is a major release that contains lots of bug fixes and improvements, some of which introduce backward incompatible changes with respect to Axis2 1.6.x (as described below).
More specifically:
.. application code should no longer assume that the Attachments object is set on the message context and contains all MIME parts of the message. Note that as of Axis2 1.7.0, this assumption is still true (because the JAX-WS implementation internally relies on this), but this will change in a subsequent release.
Class apache/axis2/builder/MIMEBuilder.java is mentioned on this JIRA issue.
You have to refactor your implementation to be able to upgrade the version.
I'm porting a desktop JavaFx Application that requires Jackson to GluonMobile, it's my first time using this platform and I end up on the next stacktrace with a NoClassDefFoundError.
I would like to know if this requires a feature not supported by GluonMobile or if I just forgot to include something properly.

This solution is quite a workaround that requires a bit of work.
Fixes Jackson 2.9.5 to work in gluon jfxmobile-plugin 1.3.10.
To fix jackson-databind to be able build immutable objects with a single constructor.
1.1 Drop the usage of the JDK8 module parameter-names since this requires a non implemented VM feature.
Use instead java.beans.ConstructorProperties.
1.2 Jackson uses for ConstructorProperties support some Interfaces from JDK8 that can be safety included as part of your project.
java.beans.ConstructorProperties
java.beans.Transient
1.3 Force link JDK7 support
forceLinkClasses = [
'com.fasterxml.jackson.databind.ext.Java7SupportImpl',
]
To fix jackson-datatype-jsr310.
2.1 It uses some JDK8 interfaces that can be safety included in your project.
java.util.function.ToIntFunction
java.util.function.ToLongFunction
2.2 It uses some JDK8 methods that can be safety substituted by JDK6-7 implementations, simply include in your project the java files and look up the pre-JDK8 back ports of the Time API.
JavaTimeModule.java
SerializerToPach.java
3.3 Point your own JavaTimeModule to your own serializer.
3.4 Register in your ObjectMapper your own JavaTimeModule.
Voila, now you can use the lattest Jackson to create immutable objects and use JDK8 Time classes in gluon jfxmobile-plugin 1.x
HAdoop single node cluster is working fine. HAdoop is working fine. JPS/Web interface of hadoop working fine.
I have done set up of hive.
When am entering into hive from hadoop its giving me below error :
"Exception in thread "main" java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory
Can someone help me in this case
If you get the slf4j IllegalAccessError shown above, then you are using an older version of slf4j-api, e.g. 1.4.3, with a new version of a slf4j binding, e.g. 1.5.6. As mentioned in the slf4j faq on IllegalAccessError, this typically occurs when your Maven pom.ml file incorporates hibernate 3.3.0 which declares a dependency on slf4j-api version 1.4.2. If your pom.xml declares a dependency on an slf4j binding, say slf4j-log4j12 version 1.5.6, then you will get illegal access errors.
Also refer to the solution here: IllegalAccessError slf4j
