Cloudera Manager provides an integrated, easy-to-use management solution to enable data protection on the Hadoop platform. Replication Manager enables you to replicate data across data centers for disaster recovery scenarios.
Replications can include data stored in HDFS, data stored in Hive tables, Hive metastore data, and Impala metadata (catalog server metadata) associated with Impala tables registered in the Hive metastore. When critical data is stored on HDFS, Cloudera Manager helps to ensure that the data is available at all times, even in case of complete shutdown of a data center.
