hbase官方网站声称的兼容是否是100%兼容？

根据[1]中的兼容矩阵，如下:

我们采用

hadoop3.1.2

hbase2.2.4

进行测试

$HBASE_HOME/logs/hbase-appleyuchi-master-Desktop.log

报错:

根据[1]

hbase.unsafe.stream.capability.enforce=false存在丢失数据的风险，根本无法用于生产环境。

根据[2]中进行自行编译后(链接中是3.2.1的，记得要改成3.1.2)，

hbase.unsafe.stream.capability.enforce=true

下上述报错消失。

所以官网声称的兼容的意思是:

这个兼容包含了你自己编译的版本，并不是指从官网下载的就一定100%兼容。
