# Fluo YARN properties
########################

# NOTE - All properties that have a default are set with it. Uncomment
# a property if you want to use a value different than the default.
# Properties that have no default are uncommented and must be set by
# the user.

## General properties
## ------------------
## Zookeeper connection string specifying host and chroot where Fluo YARN launcher stores data.
## A chroot directory suffix (with max depth of 1) must be specified but doesn't need to be named '/fluo-yarn'.
fluo.yarn.zookeepers={{ zookeeper_connect }}/fluo-yarn

## YARN resource manager hostname. Should match 'yarn.resourcemanager.hostname' property in Hadoop's yarn-site.xml
fluo.yarn.resource.manager={{ groups['resourcemanager'][0] }}

## HDFS root path. Should be prefixed with 'fs.defaultFS' property in Hadoop's core-site.xml
fluo.yarn.dfs.root={{ hdfs_root }}/

## Oracle properties
## -----------------
## Number of oracle yarn instances
#fluo.yarn.oracle.instances=1

## Max memory of Oracle yarn containers (in MB)
#fluo.yarn.oracle.max.memory.mb=512

## Number of Oracle virtual cores
#fluo.yarn.oracle.num.cores=1

## Worker properties
## -----------------
## Number of Worker instances
fluo.yarn.worker.instances={{ groups['workers']|length }}

## Max memory of worker YARN containers (in MB). If YARN is killing worker processes consider
## increasing twill.java.reserved.memory.mb (which defaults to 200 and is set in yarn-site.xml).
## The twill.java.reserved.memory.mb config determines the gap between the YARN memory limit set
## below and the java -Xmx setting.  For example, if max memory is 1024 and twill reserved memory
## is 200, the java -Xmx setting will be 1024-200 = 824 MB.
fluo.yarn.worker.max.memory.mb={{ fluo_worker_mem_mb }}

## Number of worker virtual cores
#fluo.yarn.worker.num.cores=1
