Guys,
I've been looking at bin/ignite.sh and noticed that a random number is getting
generated to form the name of an essentially lock file. For that a java VM is
started. Eg
RANDOM_NUMBER=$("$JAVA" -cp "${CP}"
org.apache.ignite.startup.cmdline.CommandLineRandomNumberGenerator)
While the start up time of modern JVM is blazingly short (just try to time it
yourself and prepare to be really surprised) I can't help by ask why it has to
be done this way? Unix in general, and bash in particular, provide native ways
of getting random numbers. E.g.
$ echo $RANDOM
or
$ od -vAn -N4 -tu4 < /dev/urandom # (if you want get fancy)
But there should be a reason behind using UUID. What's that? Thanks!
Cos
