Comment the cache section from your app/etc/local.xml file. The cache section will be as below.

<cache>
          <backend>CACHE_BACKEND_CLASS_NAME</backend>
          <backend_options>
            <server>127.0.0.1</server>              <!-- or absolute path to unix socket -->
            <port>6379</port>
            <persistent></persistent>               <!-- Specify a unique string like "cache-db0" to enable persistent connections. -->
            <database>0</database>
            <password></password>
            <force_standalone>0</force_standalone>  <!-- 0 for phpredis, 1 for standalone PHP -->
            <connect_retries>1</connect_retries>    <!-- Reduces errors due to random connection failures -->
            <read_timeout>10</read_timeout>         <!-- Set read timeout duration -->
            <automatic_cleaning_factor>0</automatic_cleaning_factor> <!-- Disabled by default -->
            <compress_data>1</compress_data>        <!-- 0-9 for compression level, recommended: 0 or 1 -->
            <compress_tags>1</compress_tags>        <!-- 0-9 for compression level, recommended: 0 or 1 -->
            <compress_threshold>20480</compress_threshold>  <!-- Strings below this size will not be compressed -->
            <compression_lib>gzip</compression_lib> <!-- Supports gzip, lzf and snappy -->
          </backend_options>
        </cache>

It is trying to connect to the cache server which is mentioned in local.xml file. I think you took code of production setup and trying to setup in local environment. As you don't have cache in your local setup, it is unable to find the related details. Comment the cache section and clear the var folder. Then it is done.
