Apache Hadoop Distributed Copy – DistCp.

The behaviour of DistCp differs here from the legacy DistCp, in how paths are considered for copy. When copying between same major versions of Hadoop cluster e.g. between 2.X and 2.X, use hdfs protocol for better performance. Secure Copy over the wire with distcp. Why does the new DistCp use more maps than legacy DistCp? Legacy DistCp works by figuring out what files need to be actually copied to target before the copy-job is launched, and then launching as many maps as required for copy. So if a majority of the files need to be skipped because they already exist, for example, fewer maps will be needed. DistCp distributed copy is a tool used for large inter/intra-cluster copying. DistCp is very efficient because it uses MapReduce to copy the files or datasets and this means the copy operation is distributed in multiple nodes in your cluster and hence it is very effective as opposed to a hadoop fs -cp operation.

You can copy files or directories between different clusters by using the hadoop distcp command. You must include a credentials file in your copy request so the source cluster can validate that you are authenticated to the source cluster and the target cluster. I have two Hadoop clusters and both are running the same Hadoop version. I also have a user "testuser" example in both clusters so testuser keytabs is present in both. Namenode1 source clust. The most common invocation of DistCp is an inter-cluster copy: bash$ hadoop distcp hdfs://nn1:8020/foo/bar \ hdfs://nn2:8020/bar/foo This will expand the namespace under /foo/baron nn1 into a temporary file, partition its contents among a set of map tasks, and start a copy on each TaskTracker from nn1 to nn2. Note that DistCp expects absolute.

Best Practices for using DistCp to Back Up Hadoop In this post I will describe the recommended best practices for the backup of non-Isilon Hadoop environments to an EMC Isilon cluster. With its very robust erasure-coding data protection that provides greater than 80% storage efficiency, EMC Isilon is in my opinion an ideal backup target for data located on a Hadoop cluster. The hadoop distcp command is used for data migration from HDFS to the IBM Spectrum Scale™ file system and between two IBM Spectrum Scale file systems. There are no additional configuration changes. The hadoop distcp command is supported in HDFS transparency 2.7.0-2 gpfs.hdfs-protocol-2.7.0-2 and later.

Copying files between clusters - IBM.

The standard Hadoop distributed copy utility “distcp” is a good tool for doing these kinds of transfers. This utility uses Map jobs to copy files from the source cluster to all data nodes on the target cluster in parallel. For this to be possible all data nodes in each cluster must be visible to the other cluster. Apache Hadoop distcp.
