# HBase gradle examples
## Build
``` bash
git clone https://github.com/hibuz/hbase-example
cd hbase-example
# Run and Execute bash on docker container
./docker_up.sh
# Build in the docker container
./mvnw package
```
## Prepare input files into the distributed filesystem
``` bash
# Make the HDFS directories
hdfs dfs -mkdir -p /user/hadoop/wordcount/input
# Create the input files
echo "Hello World Bye World" | hdfs dfs -put - wordcount/input/file01
echo "Hello HBase Goodbye HBase" | hdfs dfs -put - wordcount/input/file02
```
## Run some of the examples provided:
``` bash
# WordCount Example
hadoop jar target/examples-0.0.1-SNAPSHOT.jar wordcount wordcount/input wordcount/output
# View the output files on the distributed filesystem:
hdfs dfs -cat wordcount/output/*
# Result of the output files
Bye 1
Goodbye 1
HBase 2
Hello 2
World 2
# Grep Example
hadoop jar target/examples-0.0.1-SNAPSHOT.jar grep wordcount/input output '([G-H])\w+'
# View the output files on the distributed filesystem:
hdfs dfs -cat output/*
# Result of the output files
2 Hello
2 HBase
1 Goodbye
```
