Method Detail

setFullFileStatus

public static void setFullFileStatus(org.apache.hadoop.conf.Configuration conf,
                                     HdfsUtils.HadoopFileStatus sourceStatus,
                                     org.apache.hadoop.fs.FileSystem fs,
                                     org.apache.hadoop.fs.Path target,
                                     boolean recursion)

Copy the permissions, group, and ACLs from a source HdfsUtils.HadoopFileStatus to a target Path. This method will only log a warning if permissions cannot be set, no exception will be thrown.

Parameters:

conf - the Configuration used when setting permissions and ACLs

sourceStatus - the source HdfsUtils.HadoopFileStatus to copy permissions and ACLs from

fs - the FileSystem that contains the target Path

target - the Path to copy permissions, group, and ACLs to

recursion - recursively set permissions and ACLs on the target Path

setFullFileStatus

public static void setFullFileStatus(org.apache.hadoop.conf.Configuration conf,
                                     HdfsUtils.HadoopFileStatus sourceStatus,
                                     String targetGroup,
                                     org.apache.hadoop.fs.FileSystem fs,
                                     org.apache.hadoop.fs.Path target,
                                     boolean recursion)

Copy the permissions, group, and ACLs from a source HdfsUtils.HadoopFileStatus to a target Path. This method will only log a warning if permissions cannot be set, no exception will be thrown.

Parameters:

conf - the Configuration used when setting permissions and ACLs

sourceStatus - the source HdfsUtils.HadoopFileStatus to copy permissions and ACLs from

targetGroup - the group of the target Path, if this is set and it is equal to the source group, an extra set group operation is avoided

fs - the FileSystem that contains the target Path

target - the Path to copy permissions, group, and ACLs to

recursion - recursively set permissions and ACLs on the target Path
