# This file contains environment variables required to run Tachyon. Copy it as tachyon-env.sh and
# edit that to configure Tachyon for your site. At a minimum,
# the following variables should be set:
#
# - JAVA_HOME, to point to your JAVA installation
# - TACHYON_MASTER_ADDRESS, to bind the master to a different IP address or hostname
# - TACHYON_UNDERFS_ADDRESS, to set the under filesystem address.
# - TACHYON_WORKER_MEMORY_SIZE, to set how much memory to use (e.g. 1000mb, 2gb) per worker
# - TACHYON_RAM_FOLDER, to set where worker stores in memory data
#
# The following gives an example:
export TACHYON_RAM_FOLDER=/mnt/ramdisk
export TACHYON_MASTER_ADDRESS=localhost
export TACHYON_UNDERFS_ADDRESS=$TACHYON_HOME/underfs
export TACHYON_UNDERFS_ADDRESS=hdfs://localhost:8020
