Download flink from
https://flink.apache.org/downloads.html
Download to hdfs home directory
Untar the file and rename the dir to flink-{version} eg: flink-1.2.0
Make the below changes to the conf file or replace the current yaml file with below
and then make the changes accordingly.
$ cd /flink-1.2.0/conf
$ cat flink-conf.yaml

# 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.

# Streaming state checkpointing
#==============================================================================
# The backend that will be used to store operator state checkpoints if
# checkpointing is enabled.
#
# Supported backends: jobmanager, filesystem, rocksdb, <class-name-of-factory>
#
#state.backend: filesystem
# Directory for storing checkpoints in a Flink-supported filesystem
# Note: State backend must be accessible from the JobManager and all TaskManagers.
# Use "hdfs://" for HDFS setups, "file://" for UNIX/POSIX-compliant file systems,
# (or any local file system under Windows), or "S3://" for S3 file system.
#
# state.backend.fs.checkpointdir: hdfs://namenode-host:port/flink-checkpoints
#==============================================================================
# Advanced
#==============================================================================
# The number of buffers for the network stack.
#
# taskmanager.network.numberOfBuffers: 2048
# Directories for temporary files.
#
# 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.
#
# If not specified, the system-specific Java temporary directory (java.io.tmpdir
# property) is taken.
#
# taskmanager.tmp.dirs: /tmp
# Path to the Hadoop configuration directory.
#
# This configuration is used when writing into HDFS. Unless specified otherwise,
# HDFS file creation will use HDFS default settings with respect to block-size,
# replication factor, etc.
#
# You can also directly specify the paths to hdfs-default.xml and hdfs-site.xml
# via keys 'fs.hdfs.hdfsdefault' and 'fs.hdfs.hdfssite'.

# fs.hdfs.hadoopconf: /path/to/hadoop/conf/
#==============================================================================
# High Availability
#==============================================================================
# The list of ZooKeeper quorum peers that coordinate the high-availability
# setup. This must be a list of the form:
#
# "host1:clientPort,host2:clientPort,..." (default clientPort: 2181)
#
# high-availability: zookeeper
# high-availability.zookeeper.quorum: localhost:2181
# high-availability.zookeeper.storageDir: hdfs:///flink/ha/
# 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
#
# high-availability.zookeeper.client.acl: open

# Flink Cluster Security Configuration (optional 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
#security.kerberos.login.keytab: /path/to/kerberos/keytab
#security.kerberos.login.principal: flink-user
#security.kerberos.login.use-ticket-cache: true
#security.kerberos.login.contexts: Client,KafkaClient
#==============================================================================
# ZK Security Configuration (optional 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
Here we have only one disk: /mnt/vol2 and hence few directories created and
if more disks available (/mnt/vol1 to /mnt/voln)then add tmp directories accordingly.
Create the dir structure mentioned above in conf in all nodes:
mkdir -p /mnt/vol2/tmp/flink-cluster-tmp-2
mkdir -p /mnt/vol2/tmp/flink-blobstore-tmp
mkdir -p /mnt/vol2/tmp/flink-blobstore-tmp-2
mkdir -p /mnt/vol2/tmp/flink-cluster-tmp
mkdir -p /mnt/vol2/tmp/flink-webclient-tmp
mkdir -p /mnt/vol2/tmp/flink-webclient-tmp-2
mkdir -p /mnt/vol2/tmp/hdfs-run-logs
mkdir -p /mnt/vol2/tmp/flink-cluster-tmp-2_1

chmod 777 /mnt/vol2/tmp/flink-cluster-tmp
chmod 777 /mnt/vol2/tmp/flink-webclient-tmp
chmod 777 /mnt/vol2/tmp/flink-webclient-tmp-2
chmod 777 /mnt/vol2/tmp/hdfs-run-logs
chmod 777 /mnt/vol2/tmp/flink-cluster-tmp-2_1
Here yarn will create the required containers for processing in each node.
Flink installation is done only in 1 node but the directories created above should
be present in all nodes where nodemanager is installed.
