Lefty Leverenz commented on HIVE-9351:
--------------------------------------
Should the new guidelines in hcatalog/src/test/e2e/templeton/README.txt be
documented in the wiki?
{code}
+Running on Tez
+1. set up Tez as in http://tez.apache.org/install.html
+2. set hive.execution.engine=tez in hive-site.xml (actually is this needed?)
+3. add hive.execution.engine=tez to templeton.hive.properties in
webhcat-site.xml
+4. add to mapred-env.sh/yarn-env.sh (as you defined these in step 1)
+export TEZ_VERSION=0.5.3
+export TEZ_JARS=/Users/ekoifman/dev/apache-tez-client-${TEZ_VERSION}
+export TEZ_CONF_DIR=${TEZ_JARS}/conf
+export
HADOOP_CLASSPATH=${TEZ_CONF_DIR}:${TEZ_JARS}/*:${TEZ_JARS}/lib/*:${HADOOP_CLASSPATH}
+(w/o this you'll see something like "java.lang.NoClassDefFoundError:
org/apache/tez/dag/api/SessionNotRunning")

> Running Hive Jobs with Tez cause templeton to never report percent complete
> ---------------------------------------------------------------------------
>
> Key: HIVE-9351
> URL: https://issues.apache.org/jira/browse/HIVE-9351
> Project: Hive
> Issue Type: Bug
> Components: WebHCat
> Affects Versions: 0.14.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Fix For: 0.15.0
>
> Attachments: HIVE-9351.patch
>
>
> Currently, when submitting Hive jobs through WebHCat and Hive is configured
> to use Tez, the "percentComplete" field returned by WebHCat is empty.
> LaunchMapper in WebHCat parses stderr of the process that it launches to
> extract map = 100%, reduce = 100% for Map/Reduce case. With Tez the content
> of stderr looks like
> {noformat}
> Map 1: -/- Reducer 2: 0/1
> Map 1: -/- Reducer 2: 0(+1)/1
> Map 1: -/- Reducer 2: 1/1
> {noformat}
> WebHCat should handle that as well.
> WebHCat will follow HIVE-8495 and report (completed tasks)/(total tasks) as a
> percentage.
