ATTACHMENT ID: 12969543 - PreCommit-HIVE-Build
> Add task queue/runtime stats per LLAP daemon to output
> ------------------------------------------------------
>
> Key: HIVE-21785
> URL: https://issues.apache.org/jira/browse/HIVE-21785
> Project: Hive
> Issue Type: Improvement
> Components: llap
> Affects Versions: 3.1.1
> Reporter: Oliver Draese
> Assignee: Oliver Draese
> Priority: Major
> Fix For: 3.1.1
>
> Attachments: HIVE-21785.patch

>
> There are several scenarios, where we want to investigate if a particular
> LLAP daemon is performing faster or slower than the others in the cluster. In
> these scenarios, it is specifically important to figure out if tasks spent
> significant time, waiting for an available executor (queued) vs. on the
> execution itself. Also, a skew in task-to-daemon assignment is interesting.
> This patch adds these statistics to the TezCounters and therefore to the job
> output on a per LLAP daemon base. Here is an example.
> {{INFO : LlapTaskRuntimeAgg by daemon:}}
> {{INFO : Count-host-1.example.com: 41}}
> {{INFO : Count-host-2.example.com: 39}}
> {{INFO : Count-host-3.example.com: 45}}
> {{INFO : QueueTime-host-1.example.com: 51437776}}
> {{INFO : QueueTime-host-2.example.com: 35758306}}
> {{INFO : QueueTime-host-3.example.com: 47168327}}
> {{INFO : RunTime-host-1.example.com: 165151539295}}
> {{INFO : RunTime-host-2.example.com: 141729193528}}
> {{INFO : RunTime-host-3.example.com: 166876988771}}
> The "Count-" are simple task counts for the appended host name (LLAP daemon)
> The "QueueTime-" values tell, how long tasks waited in the
> TaskExecutorService's queue before getting actually executed.
> The "RunTime-" values cover the time from execution start to finish (where
> finish can either be successful execution or a killed/failed execution).
> For the new counts to appear in the output, both - the preexisting
> hive.tez.exec.print.summary and the new hive.llap.task.time.print.summary
> have to be set to true.
>
> {{<property>}}
> {{ <name>hive.tez.exec.print.summary</name>}}
> {{ <value>true</value>}}
> {{</property>}}
> {{<property>}}
> {{ <name>hive.llap.task.time.print.summary</name>}}
> {{ <value>true</value>}}
> {{</property>}}
