Hyunsik Choi updated TAJO-1306:
-------------------------------
Description:
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.

> HAServiceUtil should not directly use HDFS.
