Description

These are the command line arguments for hbase from Ambari. There are a couple of corrections needed:

• There are two -Xmx settings. We should remove the -Xmx1000m
• -XX:ErrorFile=/var/log/hbase/hbase/hs_err_pid%p.log should be /var/log/hbase/hs_err_pid%p.log. we should not create the directory /var/log/hbase/hbase, so it should be /var/log/hbase.
• Make appropriate changes for other HBase defaults:
  • hbase.regionserver.handler.count = 60
  • hfile.block.cache.size = 0.40
  • hbase.hregion.max.filesize = 10737418240
  • hbase.regionserver.global.memstore.lowerLimit = 0.38
