Subject Re: Install HBase on hadoop-2.2.0
Date Fri, 25 Oct 2013 19:54:51 GMT
I see that message (about stack guard) everywhere. It does bother me, but
other things have worked. I don't know why that lib is there. It has to have
been bundled with the hadoop-2.2.0 package that I downloaded because I
didn't copy it there or anything. This was downloaded directly from the
Apache Hadoop site and the JDK is the latest available from Oracle's
website. Here's some more information if it will help (below). Thanks again:

Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library
/opt/hadoop/lib/native/libhadoop.so.1.0.0 which might have disabled stack
guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c
<libfile>', or link it with '-z noexecstack'.
