Subject [jira] [Created] (TAJO-2184) Can not run Tajo with non-default $TAJO_CONF_DIR
Date Tue, 18 Oct 2016 06:03:58 GMT
Lee Dongjin created TAJO-2184:
---------------------------------

             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}"
fi
```

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.
