huowang updated HDFS-14604:
---------------------------
Release Note: Fixed HDFS OEV deserialized edits log conversion from XML to
binary error when OP_TRUNCATE existed. (was: 修复 HDFS OEV 反序列化edits log
当存在OP_TRUNCATE 时,从xml转换成binary报错的问题,)
Description:
使用 HDFS OEV 命令处理 edits 文件,从xml格式的文件转成成binary格式的文件的时候,当xml文件中存在 OP_TRUNCATE
操作并且含有子 BLOCK的时候报错
我追踪了源码发现 blockFromXml 方法需要的是一个block 对象但是被传递的是一个 data对象,我已经解决了这个问题,并且验证了可用性,
When edits files are processed with HDFS OEV command and converted from
XML files to binary files, errors are reported when OP_TRUNCATE operation
exists in XML files and BLOCKs are included.
I tracked the source code and found that the blockFromXml method needed a
block object but was passed a data object. I have solved this problem and
verified its availability.
I will submit a patch for this as soon as possible.
