Hbase average load high in ambari

In ambari hbase avg load is high , it is 360 regions per regionserver .....what are the parameters in general I have to tune related to hbase so that hbase avg load could be less than 250 regions per regionserver.



@Anurag Mishra

Depending on your hbase version this could be a solution Hbase Region Normaliser

Simple implementation of region normalizer. Logic in use:

  • Get all regions of a given table
  • Get avg size S of each region (by total size of store files reported in RegionMetrics)
  • Seek every single region one by one. If a region R0 is bigger than S * 2, it is kindly requested to split. Thereon evaluate the next region R1
  • Otherwise, if R0 + R1 is smaller than S, R0 and R1 are kindly requested to merge. Thereon evaluate the next region R2
  • Otherwise, R1 is evaluated

Hope that helps
