hawq init cluster failed

Hi, HAWQ Developers:

   I pulled the latest 2.0-beta code. During the step "hawq init cluster",
I got a error like "Create filespace failed, please check your hdfs
settings".

   And I check the hawqAdminLogs, it shows that:

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.

Success. You can now start the database server using:

    /mnt/xiaolin/dev_hawq/hawq-2.0-dev/bin/postgres -D
/mnt/xiaolin/hawq-data-directory/masterdd
or
    /mnt/xiaolin/dev_hawq/hawq-2.0-dev/bin/pg_ctl -D
/mnt/xiaolin/hawq-data-directory/masterdd -l logfile start

waiting for server to start... done
server started
ERROR:  filespace "dfs_system" already exists
Create filespace failed, please check your hdfs settings
20151120:17:32:26:530020 hawq_init:dserver1:xiaolin-[ERROR]:-Master init
failed, exit


    Then, I connect to the master with psql, the filespace about
"template1" is:

template1=# select * from pg_filespace;
   fsname   | fsowner | fsfsys | fsrep
------------+---------+--------+-------
 pg_system  |      10 |      0 |     0
 dfs_system |      10 |  10896 |     0
(2 rows)

template1=# select * from pg_filespace_entry;
 fsefsoid | fsedbid | fselocation
----------+---------+-------------
(0 rows)

   It seems the hawqinit.sh will create the filespace "dfs_system",
https://github.com/apache/incubator-hawq/blob/master/tools/bin/lib/hawqinit.sh#L196
. But it has been created somewhere.

    Any clue for this issue?

Thanks in advance.

Oops, this is my bad. The previous master is still running. After I kill
it, and cleanup the master/segment directory, it works now.
