>
> HAServiceUtil is tightly coupled with HDFS Filesystem. We have a plan to
> implement multiple HA implementations like HDFS and Zookeeper. We need to
> abstract it to support multiple implementations.
> Also, it forces TajoClient to have Hadoop HDFS dependency. If we decouple
> using HDFS from HAServiceUtil, we can eliminate HDFS dependency from
> TajoClient.
