Failed to load native map library: libNativeMap-Linux-i386-32.so
I am trying to get the following command to run:
bin/accumulo shell -u root
and still getting the "Failed to find an available server in the list
of servers" message.
--
-- How to make libNativeMap optional?
--
In tserver_ubuntu20gb.debug.log, I am seeing this error:
Failed to load native map library
/home/ubuntu/accumulo-1.5.0-incubating-SNAPSHOT/lib/native/map/libNativeMap-Linux-i386-32.so
Uncaught exception in TabletServer.main, exiting
I read through JIRA ACCUMULO-185 at
http://www.mail-archive.com/accumulo-dev@incubator.apache.org/msg00986.html
While the JIRA comments say the lib is optional, it does not say how
to resolve the uncaught exception. I notice that the error message
says that the tablet server is exiting.

I switched to the C++ directory and ran make with these results:

I have the missing predefs.h file at
/usr/include/i386-linux-gnu/bits/predefs.h
But I don't know how to tell the accumulo make about that location.

Please let know if there is a way to resolve either of these two issues.
Thanks.

I've posting my tinkering in the hopes that someone much more
knowledge about C++ can make sense of this issue.
My bits/predefs.h file located in /usr/include/i386-linux-gnu so I
modified the nativeMap/Makefile file to include
-I/usr/include/i386-linux-gnu on the CXXFLAGS variable just as a shot
in the dark. Then I ran make again. Here are the results:

I just noticed something in the response of the make command. Notice
that it refers to amd64. The compilation should be using i386. I am
looking at the Makefile files to see if I can find the problem. I
haven't done C++ development since 1986 or so. Wish me luck.

4G is not too small.
The problem here is that Accumulo has a setting for how much memory the tablet server should try to use, in this case 1G for map memory and 500MB for block cache while the JVM is capped at 256MB. This is actually a known, old problem and the defaults need to be fixed if they haven't already.
Change -Xmx256m to -Xmx2G or some value larger than your map memory + block cache size on the line defining ACCUMULO_TSERVER_OPTS
The other option is to reduce the 1G and 500M figures, which can be done through the accumulo-site.xml file by adding or changing the following lines (I think the second value is tserver.cache.data.size but it may be named something else ... ) :
<property>
<name>tserver.memory.maps.max</name>
<value>200MB</value>
</property>
<property>
<name>tserver.cache.data.size</name>
<value>50MB</value>
</property>
In a standalone setup you don't really want to swap, so reducing the settings in accumulo-site.xml to allow everything to fit comfortably in memory is the way to go. No matter what settings you choose, the JVM max in accumulo-env.sh should be set to a greater value than the sum of the two values in accumulo-site.xml

The output is i686.

What is the output of `uname -m`, since that g++ command is still trying to
generate a 64bit executable (-m64). That could also explain the complaints
about incompatible libraries.

Re: Failed to load native map library:

You have to set JAVA_HOME to be able to make the native map library.

While this doesn't resolve the problem you have found, it is worth noting that in absence of any native map libraries the default map will be used. No configuration changes need to be made to tell the system to use the native or default maps, rather it attempts to load the native map and will fall back to the default map if necessary.
