Tsz Wo (Nicholas), SZE commented on HDFS-94:
--------------------------------------------
> I wonder why it shows a total of 17.78GB instead of 20GB
Would it be the case that you have hit some limit? The following is quoted
from [java man
page|http://java.sun.com/javase/6/docs/technotes/tools/solaris/java.html]:
{quote}
On Solaris 7 and Solaris 8 SPARC platforms, the upper limit for this value is
approximately 4000m minus overhead amounts. On Solaris 2.6 and x86 platforms,
the upper limit is approximately 2000m minus overhead amounts. On Linux
platforms, the upper limit is approximately 2000m minus overhead amounts.

> It seems that the Heap Size shown in HDFS web UI is not accurate. It keeps
> showing 100% of usage. e.g.
> {noformat}
> Heap Size is 10.01 GB / 10.01 GB (100%)
> {noformat}
