Re: Should I remove this check about compare the last and fetched
I not sure can understand your question cleanly. Can you give more information about it, just like with a good sample. Also you can forward the code what you found and think that is happened! -- Sent from: http://apache-kylin.74782.x6.nabble.com/
Re: spark task error occurs when run IT in sanbox
Seems there your Java running time environment was not clean. 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/
Re: [jira] [Created] (KYLIN-4630) 构建cube的第三步骤Extract Fact Table Distinct Columns出现kerberos错误
It looks more like Kerberos authentication failure caused by time synchronization problems. It is recommended to check whether time synchronization is working. Then you can enter the beeline connection command at the terminal which machine you running kylin to see if it works properly. Good luck! -- Sent from: http://apache-kylin.74782.x6.nabble.com/
Re: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;)
Seems version not match error. Please check guava.jar version in your hadoop environment. Try to use below command: eg. CDH Env find /opt/cloudera -name "guava*.jar" Then list the hadoop lib folder and hbase lib folder's jars, find whether their guava.jar version were same. If not sure, please use the higher version in hadoop & hbase lib. Good luck. -- Sent from: http://apache-kylin.74782.x6.nabble.com/
Re: "Extract Fact Table Distinct Columns" step runs longer
Hi vishalchm, There were so many possibilities, and I think you give message was not enough! Please tell about which version kylin you were using, and the data feature , just like the data cardinality etc. also could you upload some kylin log info which is better way to figure out the root case. -- Sent from: http://apache-kylin.74782.x6.nabble.com/
Re: "Extract Fact Table Distinct Columns" step runs longer
Hi vishalchm, Thanks for your message. I had look some info from logs, but it no complete that not found any help message. And there your data column feature see not problem. What kind of aggregation group you designed, please show it. There I find out your job is still running, if it was the problem job, can you update this job diagnose log file? -- Sent from: http://apache-kylin.74782.x6.nabble.com/
Re: Kylin Benchmarking
Hi, I think you can upload the Kylin's diagnosis package which it include logs, and then we can help you find the root case. Maybe your problem was broken by your resource or other things. -- Sent from: http://apache-kylin.74782.x6.nabble.com/
Re: "Extract Fact Table Distinct Columns" step runs longer
Hi, vishalchm: >From your reply that could be judged it maybe your resource were busy when you first time running this job. Please check it detail when next time meet the same problems. By the way, give you some tips, you can use the yarn command pull all logs from mapreduce job. Like this: yarn logs -applicationId "which job you see the mapreduce running" > /tmp/yarn.log Good luck for your travel in Kylin. -- Sent from: http://apache-kylin.74782.x6.nabble.com/
