store in parallel to reduce region open/close time".
INLINE COMMENTS
src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java:807 The
region server will retry to close the store if the previous close operation
failed. So a local thread pool makes more sense here.
src/main/java/org/apache/hadoop/hbase/HConstants.java:193 I will update to
"hbase.hstore.open.close.threads.max"

> Region servers are opening/closing each store and each store file for every
> store in sequential fashion, which may cause inefficiency to open/close
> regions.
> So this diff is to open/close each store in parallel in order to reduce
> region open/close time. Also it would help to reduce the cluster restart time.
> 1) Opening each store in parallel
> 2) Loading each store file for every store in parallel
> 3) Closing each store in parallel
> 4) Closing each store file for every store in parallel.
