现在，我想在我的 ubuntu14.04 上部署 tachyon0.8.2，我已经有 hadoop 和 spark: on master
bd@master$ jps
11871 Jps
3388 Master
2919 NameNode
3266 ResourceManager
3123 SecondaryNameNode
在奴隶上
bd@slave$ jps
4350 Jps
2778 NodeManager
2647 DataNode
2879 Worker
我编辑了taachyon-env.sh：
export TACHYON_MASTER_ADDRESS=${TACHYON_MASTER_ADDRESS:-master}
export TACHYON_UNDERFS_ADDRESS=${TACHYON_UNDERFS_ADDRESS:-hdfs://master:9000}
然后，我运行bin/tachyon formatand bin/tachyon-start.sh local。我在以下位置看不到 tachyonMaster JPS：
/usr/local/bigdata/tachyon-0.8.2 [06:06:32]
bd$ bin/tachyon-start.sh local
Killed 0 processes on master
Killed 0 processes on master
Connecting to master as bd...
Killed 0 processes on master
Connection to master closed.
[sudo] password for bd:
Formatting RamFS: /mnt/ramdisk (512mb)
Starting master @ master
Starting worker @ master
/usr/local/bigdata/tachyon-0.8.2 [06:06:54]
bd$ jps
12183 TachyonWorker
3388 Master
2919 NameNode
3266 ResourceManager
3123 SecondaryNameNode
12203 Jps
我在 master.logs 中看到了日志，我说：

这个问题我该怎么办？
