I want to install StormCrawler 2.0, but I am unable to locate the appropriate installation instructions. In particular, what versions of Apache Storm, Zookeeper, and Java is StormCrawler 2.0 compatible with?
Thanks!
The POM file for 2.0 contains the information you are after.
Java 8
Apache Storm 2.1 (likely to be upgraded to 2.2 shortly)
according to Storm's documentation ZK 3.3.3
You could have a look at Ansible Storm and see if you can get it to work with Storm 2 with a few changes?

I needed update apache storm 1.0.0 to latest version 1.x.x (1.2.3). What is the steps need? What is the changes in storm configuration file? Is there any guide that help (migration)?
thank you so much
I don't believe (but could be wrong) that there are any breaking changes in the configuration file between 1.0.0 and 1.2.3. Migration should follow the usual steps for Storm upgrades:
Upgrade your Storm hosts one at a time by
Downloading the 1.2.3 binary release
Shutting down the Storm services running on the host (e.g. workers, supervisor, Nimbus)
Extracting the 1.2.3 release, and making any adjustments to the configuration files you had in the old install
Restarting your Storm services on that host, using the new install instead of the old install
You may also want to
Upgrade your topologies to build against the version of Storm you're upgrading to (optional, but can help catch any compile-time errors in non-core modules that may have changed within the major version, such as storm-kafka-client)
This way you can upgrade with no downtime. Of course if you don't care about downtime you can just shut down the whole cluster, do the steps outlined above, then restart the cluster using the new installs.
Edit: You're asking about the full diff of configuration options between 1.2.3 and 2.0.0. You can find every configuration option for 1.2.3 here, and the full list of configuration options for 2.0.0 here and here.
In the process of using WSO2 API Mananger 1.10.0, I scanned out security vulnerabilities. These vulnerabilities occurred on tomcat. The currently embedded version of tomcat is 7.0.59. I want to know how to upgrade this tomcat to solve these security vulnerabilities, such as upgrading the version to 7.0.93 ... I tried to change the pom.xml of product-apim. The version of carbon.kernel.version was updated from 4.4.3 to 4.4.37, but there were new problems in the packaging process. I don't know whether I should update the variables of carbon.commons.version, carbon.registry.version, etc. at the same time.
You shouldn't be upgrading the tomcat version directly as you are doing.
Your WSO2-APIM is very old version which is 1.10.
At that time that tomcat 7.0.59 version was used by wso2. It's better to upgrade your WSO2-APIM to latest 2.1.0 version. Here is the link for the same.
I am using Nutch 2.3 version to crawl data. I have to add a plugin in Nutch. I have search from web. I have found some guide from web e.g. wiki.apache.org. But it is for older version of Nutch 1.x.
How I'll do it please elaborate it as I am new in this field ?
I'm trying to install this: http://asm.ow2.org/eclipse/index.html, but I get this error which makes zero sense to me.
I'm running eclipse Kepler Service Release 1, build id 20130919-0819.
Cannot complete the install because one or more required items could not be found.
Software being installed: Bytecode Outline 2.1.0 (de.loskutov.BytecodeOutline.feature.feature.group 2.1.0)
Missing requirement: Bytecode Outline 2.1.0 (de.loskutov.BytecodeOutline.feature.feature.group 2.1.0) requires 'org.eclipse.help.appserver 0.0.0' but it could not be found
After Eclipse 3.3 "org.eclipse.help.appserver" was removed. See: eclipse:help-appserver
Description: This bundle provided implementation of a Tomcat-based web server application for the Eclipse help system. This was replaced in Eclipse 3.3 with a Jetty-based application server. This bundle defines no API and has been unused in the Eclipse platform for many releases.
It seems that the Eclipse ASM Bytecode Outline plugin was not maintained for quite some time which results in all kind of compatibility problems. For newer versions of Eclipse I therefore recommend installing this alternate version instead.
Use the Eclipse marketplace to find a version for the current eclipse version.
I installed myeclipse 8.6 on windows 8. When i am adding spring 3.0 web libraries it is not supporting. But it is supporting 2.5. Can any one please tell me the solution.
Consider using the Spring Tool Suite, also known as Eclipse STS instead, see here some snapshots.
Upgrade to the latest release of MyEclipse (currently the 2014 release). It's best to keep up to date with releases as they are more likely to have recent releases of framework libraries. Your MyEclipse license allows you to install all releases of MyEclipse whilst your license is valid; licenses do not apply to a single release.
