That's my cue! :)
We have a few grids that are running Solaris. It mostly works out of
the box as long as you are aware of three things:
- There are some settings in hadoop-env.sh and in the path that
need to be dealt with. Rather than re-quote, these were added to the Hadoop
FAQ a week or two ago so definitely take a look at that.
- The native compression libraries will need to be compiled.
Depending upon what you are doing/how performant the machines are, this may or
may not make a big difference. Compiling under Solaris with gcc will work fine
(but it is gcc... ugh!). Only a few minor changes are required to compile it
with SUNWspro. [I have patches laying around here somewhere if anyone wants to
play with them.]
- The Solaris JRE is a mixed-mode implementation. So keep in
mind that -d32 and -d64 have meaning and do work as advertised. You'll likely
want to pick a bitsize and use that for all your Hadoop daemons and tasks,
especially if you plan on using any JNI like the compression libraries.
