Elliott Clark commented on HBASE-11804:
---------------------------------------
bq.Elliott Clark The default is 1/4 of the total available memory as reported
by the OS
Yeah that's a much better default than 1gig. it scales up with larger machines.
Stays small on small machine.
Users should still change it but it's better than the aging 1gig.
> Raise default heap size if unspecified

> On master running pe randomWrite with ten threads and the default heap size
> crashes the system. This works on 0.98 and before.
> It's been a long time that 1000mb has been our default. Maybe we should start
> looking at raising that limit on master.
