> Instrumentation for read/write locks in LLAP
> --------------------------------------------

>                 Key: HIVE-21204
>                 URL: https://issues.apache.org/jira/browse/HIVE-21204
>             Project: Hive
>          Issue Type: Improvement
>          Components: llap
>            Reporter: Oliver Draese
>            Assignee: Oliver Draese
>            Priority: Major
>         Attachments: HIVE-21204.1.patch, HIVE-21204.2.patch, HIVE-21204.patch

>
> LLAP has several R/W locks for serialization of updates to query tracker, file data,
....
> Instrumentation is added to monitor the
>  * total amount of R/W locks within a particular category
>  * average + max wait/suspension time to get the R/W lock
> A category includes all lock instances for particular areas (i.e. category is FileData
and all R/W locks that are used in FileData instances are accounted within the one category).
> The monitoring/accounting is done via Hadoop Metrics 2, making them accessible via JMX.
In addition, a new "locking" GET endpoint is added to the LLAP daemon's REST interface. It
produces output like the following example:
> {
>  {{  "statsCollection": "enabled",}}
>  {{  "lockStats": [}}
>  {{    {}}{{ "type": "R/W Lock Stats",}}
>  {{      "label": "FileData",}}
>  {{      "totalLockWaitTimeMillis": 0,}}
>  {{      "readLock": {}}
>  {{         "count": 0,}}
>  {{         "avgWaitTimeNanos": 0,}}
>  {{         "maxWaitTimeNanos": 0}}
>  {{      },}}
>  {{      "writeLock": {}}
>  {{         "count": 0,}}
>  {{         "avgWaitTimeNanos": 0,}}
>  {{         "maxWaitTimeNanos": 0}}
>               }
>  {{    },}}
>  {{    { "}}{{type": "R/W Lock Stats",}}
>  {{      "label": "QueryTracker",}}
>  {{      "totalLockWaitTimeMillis": 0,}}
>  {{      "readLock": {}}
>  {{         "count": 0,}}
>  {{         "avgWaitTimeNanos": 0,}}
>  {{         "maxWaitTimeNanos": 0}}
>  {{      },}}
>  {{      "writeLock": {}}
>  {{         "count": 0,}}
>  {{         "avgWaitTimeNanos": 0,}}
>  {{         "maxWaitTimeNanos": 0}}
>               }
>  {{    } }}{{]}}
> {{}}}
> To avoid the overhead of lock instrumentation, lock metrics collection is disabled by
default and can be enabled via the following configuration parameter:
>   {{hive.llap.lockmetrics.collect = true}}
>   
>
