> Throw KylinConfigCannotInitException at STEP "Extract Fact Table Distinct
> Columns" with spark
> ---------------------------------------------------------------------------------------------
>
> Key: KYLIN-4194
> URL: https://issues.apache.org/jira/browse/KYLIN-4194
> Project: Kylin
> Issue Type: Bug
> Affects Versions: v3.0.0-beta
> Reporter: wangrupeng
> Assignee: wangrupeng
> Priority: Major
> Attachments: image-2019-10-16-16-13-00-190.png, kylin_spark.log

>
> When I use spark to extract fact table distinct columns values, kylin throw
> an exception,
> org.apache.kylin.common.KylinConfigCannotInitException: Didn't find
> KYLIN_CONF or KYLIN_HOME, please set one of them,
> see more details in [^kylin_spark.log] ^^ . I tried cdh5.7 and hdp2.4, both
> platforms got this problem.
> It seems like an environment variables issue, but when I set KYLIN_CONF or
> KYLIN_HOME on each yarn cluster node, it still not work.
> As we can see from the log, this exception occurs when TrieDictionaryBuilder
> try to build Dictionary<String> objects, but cannot find KylinConfig using
> KylinConfig.getInstanceFromEnv() method.
> My solution is to add code in spark job by reset
> KylinConfig.THREAD_ENV_INSTANCE
> from hdfs metadata as the spark job's metadata is stored in hdfs.And finally
> it works fine.
