# 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
# - TACHYON_UNDERFS_HDFS_IMPL, to set which HDFS implementation to use (e.g. com.mapr.fs.MapRFileSystem,
# org.apache.hadoop.hdfs.DistributedFileSystem)
# The following gives an example:
if [[ `uname -a` == Darwin* ]]; then
# Assuming Mac OS X
export JAVA_HOME=${JAVA_HOME:-$(/usr/libexec/java_home)}
export TACHYON_RAM_FOLDER=/Volumes/ramdisk
export TACHYON_JAVA_OPTS="-Djava.security.krb5.realm= -Djava.security.krb5.kdc="
else
# Assuming Linux
