Hi
Sorry, i made a mistake, start-client.sh script is located at /iotdb-cli/cli directory, you don't need to move it to /iotdb/iotdb directory.

I'am sorry that our document has some errors which confused you, i will fix it soon. Indeed, start-server.sh script is located at /iotdb-cli/cli directory, you don't need to move it to /iotdb/iotdb directory. In root directory, you can use 'mvn clean package -Dmaven.test.skip=true' to package our project. $ pwd /workspace/incubator-iotdb $ mvn clean package -Dmaven.test.skip=true If you want to start server, you can $ cd iotdb/iotdb/bin/ $ ./start-server.sh if you want to start client, you can $ cd iotdb-cli/cli/bin/ $ ./start-client.sh -h 127.0.0.1 -p 6667 -u root -pw root I hope this can help you.

I am very interested in Apache IoTDB and I would like to contribute some codes when I am not busy with work. But I got stuck in starting the IoTDB client when following the instructions of Doc . Here are the problems I encountered during my trial : 1he location of `start-client.sh` mentioned in the document is wrong. In the document, it says `Let $IOTDB_HOME = /xxx/incubator-iotdb/iotdb/iotdb/` and we can start client using this command: `$IOTDB_HOME/bin/start-client.sh`. But in fact, this `start-client.sh` script is in the directory: ` /xxx/incubator-iotdb/iotdb-cli/cli`. Cannot find the main class `org.apache.iotdb.cli.client.Client` error. When I try to start the client, it will throw this exception mentioned above. After looking into the script named `start-client.sh`, I found the following codes: ``` MAIN_CLASS=org.apache.iotdb.cli.client.Client CLASSPATH="" for f in ${IOTDB_HOME}/lib/*.jar; do CLASSPATH=${CLASSPATH}":"$f done ``` So the reason is that the required jars to start IoTDB client are not in the correct lib directory. After I copy all the jars in `/xxx/incubator-iotdb/iotdb-cli/cli/lib` to `/xxx/incubator-iotdb/iotdb/iotdb/lib`, this problem is solved. 3. After solving the problem in Step 2, I can finally start the client. But unfortunately, it hangs: And there is also an exception thrown in IoTDB server: I don't know what caused this problem, and please help me out. Thanks! Jenson
