I'm having a problem learning to upgrade to log4j2. Before, I used log4j 1 with apache servicemix 6.1.2, when I upgraded to log4j 2, I got an incompatibility error. I am learning to run the application on apache servicemix 7.0.1 to get the latest version of log4j2 .
I have read the document but do not understand which version of servicemix 7.0.1 uses log4j. Can anyone help me?
Im getting issues while using spark3.0 for reading elastic.
My elasticsearch version 7.6.0
I used elastic jar of the same version.
Please suggest a solution.
Spark 3.0.0 relies on Scala 2.12, which is not yet supported by Elasticsearch-hadoop. This and a few further issues prevent us from using Spark 3.0.0 together with Elasticsearch. If you want to compile it yourself, there is a pull-request on elasticsearch-hadoop (https://github.com/elastic/elasticsearch-hadoop/pull/1308) which should at least allow using scala 2.12. Not sure if it will fix the other issues as well.
It's officially released for spark 3.0
Enhancements:
https://www.elastic.co/guide/en/elasticsearch/hadoop/7.12/eshadoop-7.12.0.html
Maven Repository:
https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch-spark-30_2.12/7.12.0
It is not official for now, but you can compile the dependency on
https://github.com/elastic/elasticsearch, the steps are
git clone https://github.com/elastic/elasticsearch.git
cd elasticsearch-hadoop/
vim ~/.bashrc
export JAVA8_HOME=/usr/lib/jvm/java-8-openjdk-amd64/
source ~/.bashrc
./gradlew elasticsearch-spark-30:distribution --console=plain
and finally you can find .jar package in folder: "elasticsearch-hadoop\spark\sql-30\build\distributions", elasticsearch-spark-30_2.12-8.0.0-SNAPSHOT.jar is the es packages
I am using Apache Zeppelin 0.7.3 and would like to use the volume-leaflet visualization.
volume leaflet npm package info
The above npm package info states at the bottom of the page:
Compatibility
Requires Zeppelin 0.8.0-SNAPSHOT+
So the npm package apparently requires Zeppelin 0.8.0 but I can find no information on Zeppelin's web page on how to download/install 0.8. The latest available version of Zeppelin is 0.7.3. What am I missing here?
And yes, I have tried volume-leaflet with 0.7.3 but had some challenges.
Thanks in advance for any feedback.
Zeppelin 0.8 is still in development. The active documentation can be found here: https://zeppelin.apache.org/docs/0.8.0-SNAPSHOT/. I am not aware of any nightly-builds, so you will need to build zeppelin on your own, see How to build.
However some of the Helium Plugins work with smaller Zeppelin versions, even if they claim not to. You can try this by adding the package specification to the helium.json. I did explain that at a conference lately.
Currently, I have installed Spark 1.5.0 version on AWS using spark-ec2.sh script.
Now, I want to upgrade my Spark version to 1.5.1. How do i do this? Is there any upgrade procedure or do i have to build it from scratch using the spark-ec2 script? In that case i will lose all my existing configuration.
Please Advise
Thanks
1.5.1 has identical configuration fields with the 1.5.0, I am not aware of any automation tools, but upgrade should be trivial. C/P $SPARK_HOME/conf should suffice. Back up the old files, nevertheless.
I am using cassandra 2.0.5 on Centos 6.5 and OpsCenter 4 worked fine until i updated OpsCenter to version 4.1 . I access OpsCenter page, click on manage existing cluster and give the ip address of my node (127.0.0.1) and it gives me the following: "Error creating cluster: max() arg is an empty sequence".
Any clues ?
The bug is on 4.1.0, and is affecting those running Python 2.6. The complete fix for this is 4.1.1 (http://www.datastax.com/dev/blog/opscenter-4-1-1-now-available). To workaround this issue on 4.1.0, users should disable the auto-update feature, and manually re-populate the latest definitions. This will only need to be done once. This doesn't need to be done with 4.1.1, and that's the best fix. See the Known issues of the release notes (http://www.datastax.com/documentation/opscenter/4.1/opsc/release_notes/opscReleaseNotes410.html)
Add the following to opscenterd.conf to disable auto-update:
[definitions]
auto_update = False
Manually download the definition files
for tarball installs:
cd ./conf/definitions
for packages installs:
cd /etc/opscenter/definitions
Apply the latest definitions
curl https://opscenter.datastax.com/definitions/4.1.0/definition_files.tgz | tar xz
Restart opscenterd
I jus had today the same problem that you. I downloaded an older versions of opscenter (particulary version 4.0.2) from http://rpm.datastax.com/community/noarch/ and the error has gone.
I am also using the sam cassandra version and also on centos
