[hbase] branch HBASE-22120 updated (20c59d8 -> 6be338c)
This is an automated email from the ASF dual-hosted git repository.
zhangduo pushed a change to branch HBASE-22120
in repository https://gitbox.apache.org/repos/asf/hbase.git.
omit 20c59d8 HBASE-25373 Remove HTrace completely in code base and try to make use of OpenTelemetry
add 772350b HBASE-25419 Remove deprecated methods in RpcServer implementation (#2791)

add d13010f Revert "[PATCH] Add "regexstringnocase" to ParseFilter for case-insensitivity (#2784)"
add 904b555 HBASE-25084 Add "regexstringnocase" to ParseFilter for case-insensitivity (#2784)
add f8bd228 HBASE-24620 : Add a ClusterManager which submits command to ZooKeeper and its Agent which picks and execute those Commands (#2299)
add 56f1dbd HBASE-25425 Some notes on RawCell (#2797)
add dcb38f4 HBASE-25371: When openRegion fails during initial verification(before… (#2785)
new 6be338c HBASE-25373 Remove HTrace completely in code base and try to make use of OpenTelemetry
This update added new revisions after undoing existing revisions.
That is to say, some revisions that were in the old version of the
branch are not in the new version. This situation occurs
when a user --force pushes a change and generates a repository
containing something like this:
* -- * -- B -- O -- O -- O (20c59d8)
\
N -- N -- N refs/heads/HBASE-22120 (6be338c)
You should already have received notification emails for all of the O
revisions, and so the following emails describe only the N revisions
from the common base, B.
Any revisions marked "omit" are not gone; other references still
refer to them. Any revisions marked "discard" are gone forever.
The 1 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails. The revisions
listed as "add" were already present in the repository and have only
been added to this reference.
