----------------------------------------------
Summary: Refactor the way the CompactedHFileDischarger threads are
created
Key: HBASE-15027
URL: https://issues.apache.org/jira/browse/HBASE-15027
Project: HBase
Issue Type: Bug
Reporter: ramkrishna.s.vasudevan
Assignee: ramkrishna.s.vasudevan
Fix For: 2.0.0
As per suggestion given over in HBASE-14970, if we need to create a single
thread pool service for the CompactionHFileDischarger we need to create an
exectuor service in the RegionServer level and create discharger handler
threads (Event handlers) and pass the Event to the new Exectuor service that we
create for the compaction hfiles discharger. What should be the default number
of threads here? If a HRS holds 100 of regions - will 10 threads be enough?
This issue will try to resolve this with tests and discussions and suitable
patch will be updated in HBASE-14970 for branch-1 once this is committed.
