You can list all clusters currently running in your account by running:
cluster <- getClusterList()
To view details about your cluster:
cluster <- getCluster("pool-001")
At some point, you may also want to resize your cluster manually. You can do this simply with the command resizeCluster.
cluster <- makeCluster("cluster.json")
# resize so that we have a min of 10 dedicated nodes and a max of 20 dedicated nodes
# AND a min of 10 low priority nodes and a max of 20 low priority nodes
resizeCluster(
cluster,
dedicatedMin = 10,
dedicatedMax = 20,
lowPriorityMin = 10,
lowPriorityMax = 20,
algorithm = 'QUEUE',
timeInterval = '5m' )
If your cluster is using autoscale but you want to set it to a static size of 10, you can also use this method:
# resize to a static cluster of 10
resizeCluster(cluster,
dedicatedMin = 10,
dedicatedMax = 10,
lowPriorityMin = 0,
lowPriorityMax = 0)
You can download files from a specific node.
getClusterFile(
cluster,
"tvm-3601533753_1-20180813t211014z",
"startup/stdout.txt")
