Shaofeng SHI commented on KYLIN-3139:
-------------------------------------
Hi Vsevolod, I also encountered this issue before in a read/write separated
deployment, my solution was adding "hdp.version" as a property in Kylin's
conf/kylin_job_conf.xml, so didn't think it be a problem.
The patch looks good to me, it won't break other Hadoop distributions, and not
introduce Java code change to Kylin.
[[email protected]] Yang, can you review the patch also?
> Failure in map-reduce job due to undefined hdp.version variable when using

> Key: KYLIN-3139
> URL: https://issues.apache.org/jira/browse/KYLIN-3139
> Project: Kylin
> Issue Type: Bug
> Components: General
> Affects Versions: v2.2.0
> Environment: HDP 2.5.6, two cluster setup, Kylin 2.2.0 in a cluster
> with Hive only, remote HBase cluster for data storage
> Reporter: Vsevolod Ostapenko
> Assignee: Vsevolod Ostapenko
> Priority: Minor
> Labels: hdp
> Attachments: KYLIN-3139.master.001.patch
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> When running on top of HDP stack and using a setup where Hive and HBase run
> in different clusters cube build/refresh fails on the step "Extract Fact
> Table Distinct Columns" with the error
> {quote}java.lang.IllegalArgumentException: Unable to parse
> '/hdp/apps/$\{hdp.version\}/mapreduce/mapreduce.tar.gz#mr-framework' as a
> URI, check the setting for mapreduce.application.framework.path{quote}
> Based on existing JIRA discussions in Ambari project, it's responsibility of
> a service to set hdp.version Java property. When HBase is not installed as a
> service in a cluster where Kylin server is running, hbase launcher (invoked
> by kylin.sh) does not set this property (presumably because HBase in that
> case is just a client and not a service).
> The only suitable workaround found so far is to set property as part of the
> conf/setenv.sh script.
> In order to avoid hard coding of the HDP version info, suggested change to
> setenv.sh will attempt to detect HDP version at run-time. It should work for
> all released HDP version from 2.2.x to 2.6.x
> In addition to that, it will also try to locate and set Java native library
> path, when running on top of HDP.
