+# The external address of the host on which the JobManager runs and can be
+# reached by the TaskManagers and any clients which want to connect. This setting
+# is only used in Standalone mode and may be overwritten on the JobManager side
+# by specifying the --host <hostname> parameter of the bin/jobmanager.sh executable.
+# In high availability mode, if you use the bin/start-cluster.sh script and setup
+# the conf/masters file, this will be taken care of automatically. Yarn/Mesos
+# automatically configure the host name based on the hostname of the node where the
+# JobManager runs.

+#

+
+
+# ACL options are based on https://zookeeper.apache.org/doc/r3.1.2/zookeeperProgrammers.html#sc_BuiltinACLSchemes
+# It can be either "creator" (ZOO_CREATE_ALL_ACL) or "open" (ZOO_OPEN_ACL_UNSAFE)
+# The default value is "open" and it can be changed to "creator" if ZK security is enabled

+
+# Override the directories for temporary files. If not specified, the
+# system-specific Java temporary directory (java.io.tmpdir property) is taken.
+#
+# For framework setups on Yarn or Mesos, Flink will automatically pick up the
+# containers' temp directories without any need for configuration.
+#
+# Add a delimited list for multiple directories, using the system directory
+# delimiter (colon ':' on unix) or a comma, e.g.:
+#     /data1/tmp:/data2/tmp:/data3/tmp
+#
+# Note: Each directory entry is read from and written to by a different I/O
+# thread. You can include the same directory multiple times in order to create
+# multiple I/O threads against that directory. This is for example relevant for
+# high-throughput RAIDs.
+#
+# io.tmp.dirs: /tmp
+
+# The classloading resolve order. Possible values are 'child-first' (Flink's default)
+# and 'parent-first' (Java's default).
+#
+# Child first classloading allows users to use different dependency/library
+# versions in their application than those in the classpath. Switching back
+# to 'parent-first' may help with debugging dependency issues.
+#
+# classloader.resolve-order: child-first
+
+# The amount of memory going to the network stack. These numbers usually need 
+# no tuning. Adjusting them may be necessary in case of an "Insufficient number
+# of network buffers" error. The default min is 64MB, the default max is 1GB.

+
+#==============================================================================
+# Flink Cluster Security Configuration
+#==============================================================================
+
+# Kerberos authentication for various components - Hadoop, ZooKeeper, and connectors -
+# may be enabled in four steps:
+# 1. configure the local krb5.conf file
+# 2. provide Kerberos credentials (either a keytab or a ticket cache w/ kinit)
+# 3. make the credentials available to various JAAS login contexts
+# 4. configure the connector to use JAAS/SASL
+
+# The below configure how Kerberos credentials are provided. A keytab will be used instead of
+# a ticket cache if the keytab path and principal are set.
+
+# security.kerberos.login.use-ticket-cache: true
+# security.kerberos.login.keytab: /path/to/kerberos/keytab
+# security.kerberos.login.principal: flink-user
+
+# The configuration below defines which JAAS login contexts
+
+# security.kerberos.login.contexts: Client,KafkaClient
+
+#==============================================================================
+# ZK Security Configuration
+#==============================================================================
+
+# Below configurations are applicable if ZK ensemble is configured for security
+
+# Override below configuration to provide custom ZK service name if configured
+# zookeeper.sasl.service-name: zookeeper
+
+# The configuration below must match one of the values set in "security.kerberos.login.contexts"
+# zookeeper.sasl.login-context-name: Client
+
+#==============================================================================
+# HistoryServer
+#==============================================================================
+
+# The HistoryServer is started and stopped via bin/historyserver.sh (start|stop)
+
+# Directory to upload completed jobs to. Add this directory to the list of
+# monitored directories of the HistoryServer as well (see below).
+#jobmanager.archive.fs.dir: hdfs:///completed-jobs/
+
+# The address under which the web-based HistoryServer listens.
+#historyserver.web.address: 0.0.0.0
+
+# The port under which the web-based HistoryServer listens.
+#historyserver.web.port: 8082
+
+# Comma separated list of directories to monitor for completed jobs.
+#historyserver.archive.fs.dir: hdfs:///completed-jobs/
