             Summary: Can not run Tajo with non-default $TAJO_CONF_DIR
                 Key: TAJO-2184
                 URL: https://issues.apache.org/jira/browse/TAJO-2184
             Project: Tajo
          Issue Type: Bug
          Components: conf and scripts
            Reporter: Lee Dongjin
            Priority: Minor

When running start-tajo with non-default TAJO_CONF_DIR, it fails to start 
workers; More precisely, it tries to start workers with default TAJO_CONF_DIR 
(=${TAJO_HOME}/conf) and fails.

The missing of --conf parameter in start-tajo.sh causes this problem. For 
reference, I hereby attach the similar shell code from Hadoop project[^1] - you 
can see '--conf' is configured here, to run workers via SSH.

# start hdfs daemons if hdfs is present
if [[ -f "${HADOOP_HDFS_HOME}/sbin/start-dfs.sh" ]]; then
  "${HADOOP_HDFS_HOME}/sbin/start-dfs.sh" --config "${HADOOP_CONF_DIR}"

This update gives any significant improvements on performance or user 
convenience, but it will greatly help the users who try to update Tajo version 
with legacy configurations or who tries debugging Tajo.
