---------------------------------
Summary: Add param for bulkload wait duration in HRegion.
Key: HBASE-13530
URL: https://issues.apache.org/jira/browse/HBASE-13530
Project: HBase
Issue Type: Improvement
Components: regionserver
Affects Versions: 0.98.12
Reporter: Victor Xu
Priority: Minor
Fix For: 0.98.13
In our scenario, incremental read/write operations and complete bulkload
operations are mixed together. Bulkload needs write lock while read/write and
flush/compact need read lock. When a region is compacting, the bulkload could
hang at writeLock.tryLock(waitDuration, TimeUnit) method. The original default
waitDuration is 60sec (from 'hbase.busy.wait.duration'), and this could block
all read/writes operations from acquiring read lock for 1 minute. The chances
of this scenario become high when compaction speed limit feature(HBASE-8329) is
used.
Maybe we need to decrease the wait duration ONLY for bulkload, and let
read/write keep theirs. So I add this param('hbase.bulkload.wait.duration') to
tune wait duration for bulkloading. Of course, it is a table level setting, and
the default value is from original logic.
