> 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-21204.4.patch, HIVE-21204.5.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}}
>
>
