HBase. Do not use this configuration for production nor for
|
||||
evaluating HBase performance.</para>
|
||||
|
||||
<para>Once you have confirmed your HDFS setup, edit
|
||||
<filename>conf/hbase-site.xml</filename>. This is the file into
|
||||
<para>First, confirm your local HDFS setup. Below is an example <filename>conf/hdfs-site.xml</filename>. Note
|
||||
that the replication is set to 1 because this is a pseudo-distributed setup. The properties <varname>dfs.name.dir</varname>
|
||||
and <varname>dfs.data.dir</varname> are being set explicitly, the latter being where HDFS data will exist on your machine.
|
||||
</para>
|
||||
<para>Next, configure HBase for usage. Below is an example <filename>conf/hbase-site.xml</filename>. Note
|
||||
that the <varname>hbase.rootdir</varname> property points to the local HDFS instance. This is the file into
|
||||
which you add local customizations and overrides for
|
||||
<xreg linkend="hbase_default_configurations" /> and <xref linkend="hdfs_client_conf" />. Point HBase at the running Hadoop HDFS
|
||||
instance by setting the <varname>hbase.rootdir</varname> property.
|
||||
This property points HBase at the Hadoop filesystem instance to use.
|
||||
For example, adding the properties below to your
|
||||
<filename>hbase-site.xml</filename> says that HBase should use the
|
||||
<filename>/hbase</filename> directory in the HDFS whose namenode is
|
||||
at port 8020 on your local machine, and that it should run with one
|
||||
replica only (recommended for pseudo-distributed mode):</para>
