README
To get the native library working on the MiniAccumuloCluster, you must do a couple of things
1 - Actually build the libaccumulo shared library. This requires 'make' and 'g++' to be installed
2 - Use a MiniAccumuloConfig and call setNativeLibPaths(directory) on it, where directory is the location of the
libaccumulo library. Then use that config object when creating a MiniAccumuloCluster.
This sample does this for you, based on Accumulo 1.6.2 by default. Maven will download the appropriate
accumulo-native.tar.gz, extract it, and then call 'make' to build libaccumulo. A MiniAccumuloCluster will be configured
and started, then an Accumulo Shell will be opened into that MAC.
RUNNING:
mvn clean test
As the shell is starting up, you will see a log message with a directory for the MAC. Look for something like
2016-02-24 09:11:15,077 INFO [main] nativemaps.MiniAccumuloClusterNativeTest (MiniAccumuloClusterNativeTest.java:startShell(43)) - MAC temp folder is /var/folders/2y/n9lzqm2x10lfxqm9n40xvfvw0000gn/T/1456323064734-0
2016-02-24 09:11:15,077 INFO [main] nativemaps.MiniAccumuloClusterNativeTest (MiniAccumuloClusterNativeTest.java:startShell(44)) - Go there to look at logs
While the shell is running, if you change to the directory, then change to logs directory, you will see 2
files TableServer_<somenumber>.out. These are the tserver logs for the 2 tservers that are started.
If native libraries are loaded correctly, will see something like
2016-02-24 09:11:10,771 INFO [org.apache.accumulo.tserver.TabletServer] tserver.NativeMap (NativeMap.java:<clinit>(82)) - Loaded native map shared library from /Users/mjwall/NetBeansProjects/MAC-nativemaps/target/build-native/accumulo-native-1.6.2:/Users/mjwall/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:.
If there was an error loading the native library, you will see something like this
