Hi

 

  I'm using a hbase0.94.2 cluster, which has 3 zookeepers, 17
regionservers, about 40000 regions. each regionserver has about 2300
regions.

  Maybe the cluster has too many regions. 

  1、If a regionserver die,how long  hmaster reassign the regionserver's
2300 regions .

  If I restart hbase, how long will it  take.  

Can I estimate it

 

  2、Can I set hbase.hregion.max.filesize to 10G in hbase0.94.2

 

Thanks
