Installing the HBase Shell for Cloud Bigtable

The HBase shell is a command-line tool that performs administrative tasks, such as creating and deleting tables. The Cloud Bigtable HBase client for Java makes it possible to use the HBase shell to connect to Cloud Bigtable.

This page describes how to install the HBase shell, along with the Cloud Bigtable HBase client for Java, on a Compute Engine instance or on your own machine. You do not need to install any other HBase dependencies, such as Apache ZooKeeper. The Cloud Bigtable HBase client for Java does not require these additional dependencies.


Before you start

Before you start, you'll need to complete the following tasks:

Installing Java

To use the HBase shell with the Cloud Bigtable HBase client for Java, you must install a Java 8 runtime environment. Other versions of Java are not supported.

If you're installing the HBase shell on a Debian or Ubuntu system, you can install the Java 8 JRE by running the following commands:

sudo apt-get update
sudo apt-get install openjdk-8-jre-headless

For other operating systems, you can download and install the Java JRE.

Obtaining credentials

When you install the Cloud Bigtable HBase client for Java on your own machine, you need to obtain user access credentials for your Google Cloud Platform resources.

To obtain credentials, run the following command:

gcloud beta auth application-default login

The command opens your web browser. Choose your Google account if prompted, then click Allow to authorize access to your account.

Setting up the HBase shell

Downloading required files

  1. From the command line, download Apache HBase to any directory:

    curl -f -O
    tar xvf hbase-1.2.1-bin.tar.gz
  2. Create a directory for the Cloud Bigtable HBase client for Java, then download the Cloud Bigtable JAR file to the directory:

    mkdir -p hbase-1.2.1/lib/bigtable
    curl \
        -f -o hbase-1.2.1/lib/bigtable/bigtable-hbase-1.2-0.9.3.jar

  3. Download the dependencies for the Cloud Bigtable HBase client for Java:

    curl \
        -f -o hbase-1.2.1/lib/netty-tcnative-boringssl-static-1.1.33.Fork19.jar

Editing configuration files

  1. Open the file hbase-1.2.1/conf/hbase-site.xml in a text editor. Add properties to the <configuration> element as shown below, replacing [VALUES_IN_BRACKETS] with the correct values for your cluster:


  2. Open the file hbase-1.2.1/conf/ in a text editor. Add the following lines to the end of the file:

    export HBASE_CLASSPATH="$(pwd)/lib/bigtable/bigtable-hbase-1.2-0.9.3.jar:\
    export HBASE_OPTS="${HBASE_OPTS} -Xms1024m -Xmx2048m"

Setting the JAVA_HOME environment variable

Your shell's JAVA_HOME environment variable should be set to the location where your Java runtime environment is located.

To find the current value of JAVA_HOME:

echo ${JAVA_HOME}

If this command does not print any output, the variable is not set.

To set the value on Debian or Ubuntu:

export JAVA_HOME=$(update-alternatives --list java | tail -1 | sed -E 's/\/bin\/java//')

A typical value on Debian or Ubuntu is /usr/lib/jvm/java-8-openjdk-amd64/jre.

To set the value on OS X (requires Xcode's command-line tools):

export JAVA_HOME=$(/usr/libexec/java_home)

A typical value on OS X is /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home.

After you set the value of JAVA_HOME, run the following command to ensure that the value refers to the appropriate Java version:

${JAVA_HOME}/bin/java -version

Testing your configuration settings

The Cloud Bigtable client includes a utility that tests your configuration settings and displays an error if they are incorrect. Running this utility makes it much easier to detect issues with your settings.

To test your configuration, change to the hbase-1.2.1 directory, then run the utility:

cd hbase-1.2.1

The utility attempts to connect to your Cloud Bigtable instance. If successful, the utility displays a list of tables in the instance's cluster. If the utility cannot connect, it displays a stack trace that identifies the cause of the error. Use the information from the utility to edit your hbase-site.xml file as necessary.

Now that you've verified your configuration settings, you're ready to use the HBase shell to connect to your Cloud Bigtable cluster.

Connecting to a Cloud Bigtable instance

You can use the HBase shell to connect to your Cloud Bigtable instance, get information about your existing tables, and create new tables. See "Managing Tables" for more information about commonly used commands.

To start the HBase shell, run the following command from the hbase-1.2.1 directory:

./bin/hbase shell

The HBase shell displays a warning, which is normal. The shell prompt then appears:


If you get an error message that begins with NativeException, and the shell exits immediately, double-check all of the values in your hbase-site.xml and files.

Now that you've started the HBase shell, try running the following commands:

  • To list your tables, type list and press Enter. If you haven't created any tables yet, the HBase shell displays a message similar to the following:

    0 row(s) in 1.3580 seconds
    => []
  • To create a table, use the create command. For example, to create a table named my-table, with one column family named cf1:

    create 'my-table', 'cf1'

    The shell displays a message similar to the following:

    0 row(s) in 1.5210 seconds
    => Hbase::Table - my-table
  • To add data to a table, use the put command. For example, to put the value test-value in the row r1, using the column family cf1 and the column qualifier c1:

    put 'my-table', 'r1', 'cf1:c1', 'test-value'

    You can then use the scan command to scan the table and read the data you added:

    scan 'my-table'

    The shell displays output similar to the following:

     r1      column=cf1:c1, timestamp=1430687836046, value=test-value
    1 row(s) in 0.6260 seconds
  • To drop a table, use the disable command to disable the table, followed by the drop command. For example, to drop the table my-table:

    disable 'my-table'
    drop 'my-table'
  • To exit the HBase shell, type exit and press Enter.

While the HBase shell is running, you can type help to get usage instructions. See the HBase documentation for additional information.
