Description

I tried to build and use Alluxio, but it failed:

[sekikn@localhost bigtop]$ ./gradlew bigtop-utils-rpm
[sekikn@localhost bigtop]$ ./gradlew alluxio-rpm
[sekikn@localhost bigtop]$ sudo yum -y install output/alluxio/noarch/alluxio-1.0.1-1.el6.noarch.rpm output/bigtop-utils/noarch/bigtop-utils-1.2.0-1.el6.noarch.rpm 
[sekikn@localhost bigtop]$ sudo /usr/lib/alluxio/bin/alluxio format
cat: /etc/alluxio/conf/workers: No such file or directory
Formatting Alluxio Master @ localhost
[sekikn@localhost bigtop]$ sudo /etc/init.d/alluxio-master start
Starting Alluxio master (alluxio-master):                  [  OK  ] # seemed to start successfully
[sekikn@localhost bigtop]$ echo $?
1                                                                   # but actually it failed
[sekikn@localhost bigtop]$ ps aux | grep alluxio | grep -v grep
[sekikn@localhost bigtop]$ 

It seems to be caused by a wrong option for the startup command. In /etc/init.d/alluxio-master, "master Mount" is specified as the flags.

 61 EXEC_PATH="/usr/lib/alluxio/bin/alluxio-start.sh"
 62 SVC_USER=""
 63 DAEMON_FLAGS="master Mount"

 86     /bin/bash -c "nohup nice -n 0 \
 87         ${EXEC_PATH} ${DAEMON_FLAGS} \
 88         > $LOG_FILE 2>&1 & "

but MOPT can be specified only for all, worker and workers.

[sekikn@localhost bigtop]$ /usr/lib/alluxio/bin/alluxio-start.sh -h
Usage: alluxio-start.sh [-hNw] WHAT [MOPT] [-f]
Where WHAT is one of:
  all MOPT		Start master and all workers.
  local			Start a master and worker locally
  master		Start the master on this node
  safe			Script will run continuously and start the master if it's not running
  worker MOPT		Start a worker on this node
  workers MOPT		Start workers on worker nodes
  restart_worker	Restart a failed worker on this node
  restart_workers	Restart any failed workers on worker nodes

MOPT is one of:
  Mount			Mount the configured RamFS. Notice: this will format the existing RamFS.
  SudoMount		Mount the configured RamFS using sudo. Notice: this will format the existing RamFS.
  NoMount		Do not mount the configured RamFS
