Getting started with Accumulo Access

This standalone Accumulo Access example has the following components.

• AccessExample Example that shows how to evaluate if data is accessible.
• pom.xml Maven build file that shows how to use Accumulo Access as a dependency
• run.sh Bash script that runs the example

To run this example clone the Accumulo Access repository and then do the following.

cd accumulo-access
# This step installs a snapshot version of the Accumulo Access library.
# This step will not longer be needed once Accumulo Access is released.
mvn install
cd contrib/getting-started
# Build the example.  If you change the example java code, run this step again.
mvn clean package
# Run the example
./run.sh

Example runs

Running with the authorizations set {BLUE,GREEN,PINK,RED} shows the complete data set because all data is accessible with these authorizations.

$ ./run.sh BLUE GREEN PINK RED
data1 : (RED&GREEN)|(BLUE&PINK)
data2 : (RED&GREEN)|(BLUE&PINK)
data3 : (RED|GREEN)&(BLUE|PINK)
data4 : (RED&GREEN)|(BLUE&PINK)
data5 : (RED|GREEN)&(BLUE|PINK)
data6 : 
data7 : PINK
data8 : RED&BLUE&GREEN&PINK
data9 : PINK|(BLUE&RED)

Running with the empty set of authorizations shows only data6 which has an empty access expression and is always accessible with any authorization set.

$ ./run.sh 
data6 : 

Running with the authorizations set {BLUE,RED}

$ ./run.sh BLUE RED
data3 : (RED|GREEN)&(BLUE|PINK)
data5 : (RED|GREEN)&(BLUE|PINK)
data6 : 
data9 : PINK|(BLUE&RED)

Running with the authorizations set {GREEN,RED}

$ ./run.sh GREEN RED
data1 : (RED&GREEN)|(BLUE&PINK)
data2 : (RED&GREEN)|(BLUE&PINK)
data4 : (RED&GREEN)|(BLUE&PINK)
data6 : 

Running with the authorizations set {PINK}

$ ./run.sh PINK
data6 : 
data7 : PINK
data9 : PINK|(BLUE&RED)
