Re: spark task error occurs when run IT in sanbox
Hi elkan: Thank you take time to reply. Just as you said, the reason is the unmatched jdk version. I just set root's JAVA_HOME to point jdk1.8, but every server in sandbox has it's own user to run it. So I should re-link the original JAVA_HOME to new one.

Please check the JAVA_HOME and PATH system variable, use the echo command see what output from them. By the way the Kylin also can run in Hadoop clusters which use JDK1.7, just a simple modify. The steps like this: 1. modify the HBase conf file which name is hbase-env.sh, add export JAVA_HOME=/path/of/jdk1.8 2. append the below configure into kylin_job_conf.xml and kylin_job_conf_inmem.xml files. mapred.child.env JAVA_HOME=/usr/lib/java/jdk1.8.0_201 yarn.app.mapreduce.am.env JAVA_HOME=/usr/lib/java/jdk1.8.0_201 Hope those can help you！ -- Sent from: http://apache-kylin.74782.x6.nabble.com/
[jira] [Created] (KYLIN-3907) Sort the cube list by create time in descending order.
Yuzhang QIU created KYLIN-3907: -- Summary: Sort the cube list by create time in descending order. Key: KYLIN-3907 URL: https://issues.apache.org/jira/browse/KYLIN-3907 Project: Kylin Issue Type: Improvement Components: REST Service Affects Versions: v2.5.2 Reporter: Yuzhang QIU Hi team: Maybe there have a use experience problem in the Web UI of cube list. We will create many cubes over time and need click "MORE" to show the lastest cube when the number cubes increate to over 15. In most cases, I think, the older cube should be steady and the new cube may need to be debuged. So, sort the cube list by create time in descending order may be better. How do you think about this?

[jira] [Created] (KYLIN-3908) KylinClient's HttpRequest.releaseConnection is not needed in retrieveMetaData & executeKylinQuery

According to HttpClient's stack trace, connections are released back to connection manager after content is consumed. So it is not necessary to call releaseConnection in retrieveMetaData & executeKylinQuery.

Thanks ShaoFeng, The plan looks good.

Now we're merging the code from the RT feature branch into the master branch. Although this feature has been in production in certain early users, it has not been widely evaluated by the community. I would like to propose releasing the alpha and beta before the GA release, just like what we did in Kylin v2.0. This is to give our users enough time to evaluate; On the other side, it gives the developers the time to hear feedback, to improve the stability/performance, catch up the documentation and others. A rough plan is: - April, 3.0 alpha release - June, 3.0 beta release - July to Aug, 3.0 GA release Before 3.0 GA, the v2.6 branch will roll out bug fix releases at a steady pace; Usually, 1 version every 1-2 months, depends on the severity of the reported issues.
