+
+The object authorization model of S3 is much different from the file
+authorization model of HDFS and traditional file systems. It is not feasible to
+persist file ownership and permissions in S3, so S3A reports stub information
+from APIs that would query this metadata:
+
+* File owner is reported as the current user.
+* File group also is reported as the current user. Prior to Apache Hadoop
+2.8.0, file group was reported as empty (no group associated), which is a
+potential incompatibility problem for scripts that perform positional parsing of
+shell output and other clients that expect to find a well-defined group.
+* Directory permissions are reported as 777.
+* File permissions are reported as 666.
+
+S3A does not really enforce any authorization checks on these stub permissions.
+Users authenticate to an S3 bucket using AWS credentials. It's possible that
+object ACLs have been defined to enforce authorization at the S3 side, but this
+happens entirely within the S3 service, not within the S3A implementation.

-
-Overview
---------
-
-[Docker](https://www.docker.io/) combines an easy-to-use interface to Linux containers with easy-to-construct image files for those containers. In short, Docker launches very light weight virtual machines.
-
-The Docker Container Executor (DCE) allows the YARN NodeManager to launch YARN containers into Docker containers. Users can specify the Docker images they want for their YARN containers. These containers provide a custom software environment in which the user's code runs, isolated from the software environment of the NodeManager. These containers can include special libraries needed by the application, and they can have different versions of Perl, Python, and even Java than what is installed on the NodeManager. Indeed, these containers can run a different flavor of Linux than what is running on the NodeManager -- although the YARN container must define all the environments and libraries needed to run the job, nothing will be shared with the NodeManager.
-
-Docker for YARN provides both consistency (all YARN containers will have the same software environment) and isolation (no interference with whatever is installed on the physical machine).
-
-Cluster Configuration
----------------------
-
-Docker Container Executor runs in non-secure mode of HDFS and YARN. It will not run in secure mode, and will exit if it detects secure mode.
-
-The DockerContainerExecutor requires Docker daemon to be running on the NodeManagers, and the Docker client installed and able to start Docker containers. To prevent timeouts while starting jobs, the Docker images to be used by a job should already be downloaded in the NodeManagers. Here's an example of how this can be done:
-
- sudo docker pull sequenceiq/hadoop-docker:2.4.1
-
-This should be done as part of the NodeManager startup.
-
-The following properties must be set in yarn-site.xml:
-
-```xml
-<property>
- <name>yarn.nodemanager.docker-container-executor.exec-name</name>
- <value>/usr/bin/docker</value>
- <description>
- Name or path to the Docker client. This is a required parameter. If this is empty,
- user must pass an image name as part of the job invocation(see below).
- </description>
-</property>
-
-<property>
- <name>yarn.nodemanager.container-executor.class</name>
- <value>org.apache.hadoop.yarn.server.nodemanager.DockerContainerExecutor</value>
- <description>
- This is the container executor setting that ensures that all
-jobs are started with the DockerContainerExecutor.
- </description>
-</property>
-```
-
-Administrators should be aware that DCE doesn't currently provide user name-space isolation. This means, in particular, that software running as root in the YARN container will have root privileges in the underlying NodeManager. Put differently, DCE currently provides no better security guarantees than YARN's Default Container Executor. In fact, DockerContainerExecutor will exit if it detects secure yarn.
-
-Tips for connecting to a secure docker repository
--------------------------------------------------
-
-By default, docker images are pulled from the docker public repository. The format of a docker image url is: *username*/*image\_name*. For example, sequenceiq/hadoop-docker:2.4.1 is an image in docker public repository that contains java and hadoop.
-
-If you want your own private repository, you provide the repository url instead of your username. Therefore, the image url becomes: *private\_repo\_url*/*image\_name*. For example, if your repository is on localhost:8080, your images would be like: localhost:8080/hadoop-docker
-
-To connect to a secure docker repository, you can use the following invocation:
-
-```
- docker login [OPTIONS] [SERVER]
-
- Register or log in to a Docker registry server, if no server is specified
- "https://index.docker.io/v1/" is the default.
-
- -e, --email="" Email
- -p, --password="" Password
- -u, --username="" Username
-```
-
-If you want to login to a self-hosted registry you can specify this by adding the server name.
-
- docker login <private_repo_url>
-
-This needs to be run as part of the NodeManager startup, or as a cron job if the login session expires periodically. You can login to multiple docker repositories from the same NodeManager, but all your users will have access to all your repositories, as at present the DockerContainerExecutor does not support per-job docker login.
-
-Job Configuration
------------------
-
-Currently you cannot configure any of the Docker settings with the job configuration. You can provide Mapper, Reducer, and ApplicationMaster environment overrides for the docker images, using the following 3 JVM properties respectively(only for MR jobs):
-
-* `mapreduce.map.env`: You can override the mapper's image by passing `yarn.nodemanager.docker-container-executor.image-name`=*your_image_name* to this JVM property.
-
-* `mapreduce.reduce.env`: You can override the reducer's image by passing `yarn.nodemanager.docker-container-executor.image-name`=*your_image_name* to this JVM property.
-
-* `yarn.app.mapreduce.am.env`: You can override the ApplicationMaster's image by passing `yarn.nodemanager.docker-container-executor.image-name`=*your_image_name* to this JVM property.
-
-Docker Image Requirements
--------------------------
-
-The Docker Images used for YARN containers must meet the following requirements:
-
-The distro and version of Linux in your Docker Image can be quite different from that of your NodeManager. (Docker does have a few limitations in this regard, but you're not likely to hit them.) However, if you're using the MapReduce framework, then your image will need to be configured for running Hadoop. Java must be installed in the container, and the following environment variables must be defined in the image: JAVA_HOME, HADOOP_COMMON_PATH, HADOOP_HDFS_HOME, HADOOP_MAPRED_HOME, HADOOP_YARN_HOME, and HADOOP_CONF_DIR
-
-Working example of yarn launched docker containers
---------------------------------------------------
-
-The following example shows how to run teragen using DockerContainerExecutor.
-
-Step 1. First ensure that YARN is properly configured with DockerContainerExecutor(see above).
-
-```xml
-<property>
- <name>yarn.nodemanager.docker-container-executor.exec-name</name>
- <value>docker -H=tcp://0.0.0.0:4243</value>
- <description>
- Name or path to the Docker client. The tcp socket must be
- where docker daemon is listening.
- </description>
-</property>
-
-<property>
- <name>yarn.nodemanager.container-executor.class</name>
- <value>org.apache.hadoop.yarn.server.nodemanager.DockerContainerExecutor</value>
- <description>
- This is the container executor setting that ensures that all
-jobs are started with the DockerContainerExecutor.
- </description>
-</property>
-```
-
-Step 2. Pick a custom Docker image if you want. In this example, we'll use sequenceiq/hadoop-docker:2.4.1 from the docker hub repository. It has jdk, hadoop, and all the previously mentioned environment variables configured.
-
-Step 3. Run.
-
-```bash
-hadoop jar $HADOOP_HOME/share/hadoop/mapreduce/hadoop-mapreduce-examples-${project.version}.jar \
- teragen \
- -Dmapreduce.map.env="yarn.nodemanager.docker-container-executor.image-name=sequenceiq/hadoop-docker:2.4.1" \
- -Dyarn.app.mapreduce.am.env="yarn.nodemanager.docker-container-executor.image-name=sequenceiq/hadoop-docker:2.4.1" \
- 1000 \
- teragen_out_dir
-```
-
- Once it succeeds, you can check the yarn debug logs to verify that docker indeed has launched containers.

+ <description>
+ Maximum amount of time in milliseconds for a block to move. If this is set
+ greater than 0, Balancer will stop waiting for a block move completion
+ after this time. In typical clusters, a 3 to 5 minute timeout is reasonable.
+ If timeout happens to a large proportion of block moves, this needs to be
+ increased. It could also be that too much work is dispatched and many nodes
+ are constantly exceeding the bandwidth limit as a result. In that case,
+ other balancer parameters might need to be adjusted.
+ It is disabled (0) by default.
