| HDFS Directory Replication Recipe |
| |
| Overview |
| This recipe implements replicating arbitrary directories on HDFS from one |
| Hadoop cluster to another Hadoop cluster. |
| This piggy backs on replication solution in Falcon which uses the DistCp tool. |
| |
| Use Case |
| * Copy directories between HDFS clusters with out dated partitions |
| * Archive directories from HDFS to Cloud. Ex: S3, Azure WASB |
| |
| Limitations |
| As the data volume and number of files grow, this can get inefficient. |
