# TiDB on HBase


**TiDB only supports HBase >= 0.98.5**

1) Build && Install pingcap/themis coprocessor to HBase:

1. git clone https://github.com/pingcap/themis.git
2. cd themis && mvn clean package -DskipTests
4. cp themis-coprocessor/target/themis-coprocessor-1.0-SNAPSHOT-jar-with-dependencies.jar $HBASE_ROOT/lib
5. Add configurations for themis coprocessor in hbase-site.xml:

```
<property>
    <name>hbase.coprocessor.user.region.classes</name>
    <value>org.apache.hadoop.hbase.themis.cp.ThemisEndpoint,org.apache.hadoop.hbase.themis.cp.ThemisScanObserver,org.apache.hadoop.hbase.regionserver.ThemisRegionObserver</value>
</property>
<property>
    <name>hbase.coprocessor.master.classes</name>
    <value>org.apache.hadoop.hbase.master.ThemisMasterObserver</value>
</property>
```

and then restart HBase.


2) Build TiDB:

```
git clone https://github.com/pingcap/tidb.git $GOPATH/src/github.com/pingcap/tidb
cd $GOPATH/src/github.com/pingcap/tidb
make
```

Run command line interpreter:

```
make interpreter
cd interpreter && ./interpreter -store hbase -dbpath localhost/tidb -dbname test
```

Enjoy it.
