Hello, I have a big problem!!!!
We deleted hbase data with " hdfs dfs -rmr -skipTrash /hbase",
Is there any way to recovery the deleted date?
Thanks a lot!

While this is an exotic situation and may not have a solution, there is
some guidance from hortonworks on manually editing the transaction log on
the namenode to enable data recovery.
https://community.hortonworks.com/articles/26181/how-to-recover-accidentally-deleted-file-in-hdfs.html
if you're able to restore the blocks on the data nodes and undo the delete
from the name node the data should be recoverable.

we have a plan:
step 1: recover fsimage with ext4magic ( a small tool to recovery
files/directory on linux platform) on namenode;
step 2: recover data on every datanode
step3: start hdfs/hbase;
is the way work?
Thanks in advance.

From https://hadoop.apache.org/docs/r1.0.4/file_system_shell.html :
If the -skipTrash option is specified, the trash, if enabled, will be
bypassed and the specified file(s) deleted immediately.

AFAIK, in order to recover data, user has to react within minutes or
seconds. But, have you checked ".Trash" folder in hdfs under hbase user or
the user that issued the rmr command.
