> Priority: Major
>
> Hi team,
> Created two hadoop clusters, one cluster is storing files in new directories
> based on TIME based directories are created in Hadoop FileSystem say
> /a/b/time/a.txt b.txt..
> For every 5 mins, compare this cluster 1 filesytem for two different
> directories whether any new directories with list of files are updated or not
> , if its updated in dir 1, then update those files only to be moved to dir 2.
> Later those new directories files copied to HDFS cluster 2 file system.
> Currently HDFS not supported hdfs dfs -diff command, Any solution for this?
> Have tried -copyFromLocal and copyToLocal command, it uses lot of diskspace
> while copying local to hdfs & hdfs to local.
