OK, it was waitForMetaOnline.
Maybe the problem is that you do have some correct procedures before
upgrading, like ServerCrashProcedure, but then you delete all the
procedure wals so the ServerCrashProcedure is also gone, so meta can
never be online.
Please check the /hbase/meta-region-server
Just post it somewhere so we can check it.

For me I've never seen people actually use the xz compression.
For size, usually people will choose gzip, and for speed, in the past
people will choose lzo and now they choose snappy or zstd.
So for me I prefer we just deprecated the xz compression immediately
and remove it 2.6.0.

In general, HBase will bundle the oldest hadoop binaries it could
support by default.
It does not mean that you should have your hadoop servers, like HDFS
or YARN, has the same version. You are free to use newer version of
hadoop to setup HDFS or YARN, as a hadoop client with lower version

Better also send the email to user@hbase to see what our users think.
I think we could change the default profile to hadoop3, but better
still have the hadoop2 profile as there could still be users on
hadoop-2.x.
We will completely drop the hadoop2 support in hbase 3.x.

I guess the problem is you exceeded the maximum size limit for
zookeeper multi operation.
I searched the code base of branch-1, you could try to set
'hbase.zookeeper.useMulti' to false in your hbase-site.xml to disable
multi so the operation could succeed. But it may introduce
inconsistency so
See https://issues.apache.org/jira/browse/HDFS-13571.

2.1 上的代码我记的不太清楚了，不过 region assign 相关 procedure 在 2.2 重新写了一遍，之前确实有 bug
很难搞定，常见的就是 region 不下线，或者一个 region 被 assign 到两台 RS 上，只能重启搞定。另外后来又在 2.3 上把存储
procedure 的部分重新实现了一遍，才算比较稳定。
所以 2.1 在大集群特别是有些过载的情况下跑 merge 确实有可能出 bug，hbck 的处理没啥问题，也只能这样搞。。。

I'm OK with this change.

And maybe we could enable github issues to let users ask questions and
report bugs there first, if we decided it is a true

hadoop3 binaries, to see if it could meet our users' requirements.

binaries for hadoop3.
