Esteban Gutierrez commented on HBASE-11804:
-------------------------------------------
[~eclark] The default is 1/4 of the total available memory as reported by the
OS, so it should be better to have a number instead of leave it as the JVM
default.
> 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.
