ok
I'd love to, but I've been a little busy lately. I'll be out in a few days.

I encountered a problem when I converted edits files from XML to binary using the HDFS oev command

Usually this conversion operation will not be a problem, but my XML culture contains an OP_TRUNCATE operation node, in this case, the error is reported, the specific error is as follows. (sorry, I can only take a screenshot because the company environment does not allow copying code, the name of the file is not NameNode's default name because I backed up the edits file for testing).
The contents of the XML file are as follows

I found the error-reporting code and found that the blockFromXml method passed the entire data node instead of the subordinate BLOCK node. I think this was the reason. So I modified the code and recompiled it. Then I installed a single node Hadoop cluster and tested the HDFS oev command conversion file successfully. This is my first time to submit a patch. My English is not particularly good, I am not sure. Should the modified code be submitted in this way?
I hope I can contribute to the community.
