Class HDFSUtil

java.lang.Object

co.cask.tephra.persist.HDFSUtil

public class HDFSUtil
extends Object

Utility for handling HDFS file lease recovery. This is a copy-n-paste fork of org.apache.hadoop.hbase.util.FSHDFSUtils from the latest HBase 0.94 version (as of 0.94.12), which contains some additional fixes not present in our current HBase dependency version -- mainly checking the return value of the DistributedFileSystem.recoverLease() call to verify that recovery succeeded.
