Deprecated Classes

Class and Description
alluxio.master.block.BlockMasterClientRestServiceHandler since version 1.4 and will be removed in version 2.0
alluxio.hadoop.FaultTolerantFileSystem as of 1.6.0. Use AlluxioFileSystem instead and configure the fault tolerant options appropriately (alluxio.zookeeper.*). An Alluxio client API compatible with Apache Hadoop FileSystem interface. Any program working with Hadoop HDFS can work with Alluxio transparently. Note that the performance of using this fault tolerant API may not be as efficient as the performance of using the Alluxio native API defined in FileSystem, which the API is built on top of. Unlike FileSystem, this class enables Zookeeper.
