----------------------------------
Summary: RegionEnvironment.offerExecutionLatency Blocks Threads
under Heavy Load
Key: HBASE-13420
URL: https://issues.apache.org/jira/browse/HBASE-13420
Project: HBase
Issue Type: Improvement
Reporter: John Leach
The ArrayBlockingQueue blocks threads for 20s during a performance run focusing
on creating numerous small scans.
I see a buffer size of (100)
private final BlockingQueue<Long> coprocessorTimeNanos = new
ArrayBlockingQueue<Long>(
LATENCY_BUFFER_SIZE);
and then I see a drain coming from
MetricsRegionWrapperImpl with 45 second executor
HRegionMetricsWrapperRunable
RegionCoprocessorHost#getCoprocessorExecutionStatistics()
RegionCoprocessorHost#getExecutionLatenciesNanos()
Am I missing something?
